August 28 is the 240th day of the year (241st in leap years) in the Gregorian calendar. There are 125 days remaining until the end of the year.

On this day in 1963, the Reverend Martin Luther King addressed the crowds assembled on the Washington Mall from the steps at the Lincoln Memorial. His speech, “I have a Dream”, is forever embedded in history and our memories as one of the great moments in the fight for civil rights. But there were many other speakers, and in particular one great performance by the “Queen of Gospel”, Mahalia Jackson. Right before Dr. King spoke, Ms. Jackson performed “How I Got Over”.

Indeed, if Martin Luther King, Jr., had a favorite opening act, it was Mahalia Jackson, who performed by his side many times. On August 28, 1963, as she took to the podium before an audience of 250,000 to give the last musical performance before Dr. King’s speech, Dr. King himself requested that she sing the gospel classic “I’ve Been ‘Buked, and I’ve Been Scorned.” Jackson was just as familiar with Dr. King’s repertoire as he was with hers, and just as King felt comfortable telling her what to sing as the lead-in to what would prove to be the most famous speech of his life, Jackson felt comfortable telling him in what direction to take that speech.

The story that has been told since that day has Mahalia Jackson intervening at a critical junction when she decided King’s speech needed a course-correction. Recalling a theme she had heard him use in earlier speeches, Jackson said out loud to Martin Luther King, Jr., from behind the podium on the steps of the Lincoln Memorial, “Tell them about the dream, Martin.” And at that moment, as can be seen in films of the speech, Dr. King leaves his prepared notes behind to improvise the entire next section of his speech-the historic section that famously begins “And so even though we face the difficulties of today and tomorrow, I still have a dream. It is a dream deeply rooted in the American dream….”

There is no embeddable video of Ms Jackson from that day but here is the inspirational song she performed that day.

August 27 is the 239th day of the year (240th in leap years) in the Gregorian calendar. There are 126 days remaining until the end of the year.

On this day in 1883, The most powerful volcanic eruption in recorded history occurs on Krakatau (also called Krakatoa), a small, uninhabited volcanic island located west of Sumatra in Indonesia, on this day in 1883. Heard 3,000 miles away, the explosions threw five cubic miles of earth 50 miles into the air, created 120-foot tsunamis and killed 36,000 people.

Krakatau exhibited its first stirrings in more than 200 years on May 20, 1883. A German warship passing by reported a seven-mile high cloud of ash and dust over Krakatau. For the next two months, similar explosions would be witnessed by commercial liners and natives on nearby Java and Sumatra. With little to no idea of the impending catastrophe, the local inhabitants greeted the volcanic activity with festive excitement.

On 27 August four enormous explosions took place at 05:30, 06:44, 10:02, and 10:41 local time. The explosions were so violent that they were heard 3,500 km (2,200 mi) away in Perth, Western Australia and the Indian Ocean island of Rodrigues near Mauritius, 4,800 km (3,000 mi) away, where they were thought to be cannonfire from a nearby ship. Each was accompanied by very large tsunamis, which are believed to have been over 30 meters (100 ft) high in places. A large area of the Sunda Strait and a number of places on the Sumatran coast were affected by pyroclastic flows from the volcano.

The pressure wave generated by the colossal final explosion radiated from Krakatoa at 1,086 km/h (675 mph). It was so powerful that it shattered the eardrums of sailors on ships in the Sunda Strait and caused a spike of more than two and half inches of mercury in pressure gauges attached to gasometers in the Jakarta gasworks, sending them off the scale. The pressure wave radiated across the globe and was recorded on barographs all over the world, which continued to register it up to 5 days after the explosion. Barograph recordings show that the shockwave from the final explosion reverberated around the globe 7 times in total. Ash was propelled to a height of 80 km (50 mi).

The eruptions diminished rapidly after that point, and by the morning of August 28 Krakatoa was silent. Small eruptions, mostly of mud, continued through October, though further reports continued through February 1884. These reports were discounted by (Rogier) Verbeek.

The combined effects of pyroclastic flows, volcanic ashes and tsunamis had disastrous results in the region. There were no survivors from 3,000 people located at the island of Sebesi, about 13 km (8.1 mi) from Krakatoa. Pyroclastic flows killed around 1,000 people at Ketimbang on the coast of Sumatra some 40 km (25 mi) north from Krakatoa. The official death toll recorded by the Dutch authorities was 36,417, although some sources put the estimate at 120,000 or more.

Ships as far away as South Africa  rocked as tsunamis hit them, and the bodies of victims were found floating in the ocean for weeks after the event. The tsunamis which accompanied the eruption are believed to have been caused by gigantic pyroclastic flows  entering the sea; each of the four great explosions was accompanied by a massive pyroclastic flow resulting from the gravitational collapse of the eruption column.

In the aftermath of the eruption, it was found that the island of Krakatoa had almost entirely disappeared, except for the southern half of Rakata cone cut off along a vertical cliff, leaving behind a 250-metre (820 ft) deep caldera.

In the year following the eruption, average global temperatures fell by as much as 1.2 C (2.2 F). Weather patterns continued to be chaotic for years, and temperatures did not return to normal until 1888.

The eruption darkened the sky worldwide for years afterwards, and produced spectacular sunsets throughout the world for many months. British artist William Ashcroft made thousands of colour sketches of the red sunsets half-way around the world from Krakatoa in the years after the eruption.

August 26 is the 238th day of the year (239th in leap years) in the Gregorian calendar. There are 127 days remaining until the end of the year.

On this day in 1920, The 19th Amendment, guaranteeing women the right to vote, is formally adopted into the U.S. Constitution by proclamation of Secretary of State Bainbridge Colby. The amendment was the culmination of more than 70 years of struggle by woman suffragists. Its two sections read simply:

“The right of citizens of the United States to vote shall not be denied or abridged by the United States or by any State on account of sex” and “Congress shall have power to enforce this article by appropriate legislation.”

America’s woman suffrage movement was founded in the mid 19th century by women who had become politically active through their work in the abolitionist and temperance movements. In July 1848, 200 woman suffragists, organized by Elizabeth Cady Stanton and Lucretia Mott, met in Seneca Falls, New York, to discuss women’s rights. After approving measures asserting the right of women to educational and employment opportunities, they passed a resolution that declared “it is the duty of the women of this country to secure to themselves their sacred right to the elective franchise.” For proclaiming a women’s right to vote, the Seneca Falls Convention was subjected to public ridicule, and some backers of women’s rights withdrew their support. However, the resolution marked the beginning of the woman suffrage movement in America.

n January 1918, the woman suffrage amendment passed the House of Representatives with the necessary two-thirds majority vote. In June 1919, it was approved by the Senate and sent to the states for ratification. Campaigns were waged by suffragists around the country to secure ratification, and on August 18, 1920, Tennessee became the 36th state to ratify the amendment, giving it the two-thirds majority of state ratification necessary to make it the law of the land.

The package containing the certified record of the action of the Tennessee legislature was sent by train to the nation’s capital, arriving in the early hours of August 26. At 8 a.m. that morning, Secretary of State Bainbridge Colby signed it without ceremony at his residence in Washington. None of the leaders of the woman suffrage movement were present when the proclamation was signed, and no photographers or film cameras recorded the event. That afternoon, Carrie Chapman Catt, head of the National American Suffrage Association, was received at the White House by President Woodrow Wilson and Edith Wilson, the first lady.

The 26th of August was proclaimed “Women’s Equality Day” in 1971 when a joint resolution, that was introduced by Rep. Bella Abzug, was passed. Each year the President issues a proclamation recognizing women’s equality.

WHEREAS, the women of the United States have been treated as second-class citizens and have not been entitled the full rights and privileges, public or private, legal or institutional, which are available to male citizens of the United States; and

WHEREAS, the women of the United States have united to assure that these rights and privileges are available to all citizens equally regardless of sex;

WHEREAS, the women of the United States have designated August 26th, the anniversary date of the passage of the Nineteenth Amendment, as symbol of the continued fight for equal rights: and

WHEREAS, the women of United States are to be commended and supported in their organizations and activities,

NOW, THEREFORE, BE IT RESOLVED, the Senate and House of Representatives of the United States of America in Congress assembled, that August 26th of each year is designated as “Women’s Equality Day,” and the President is authorized and requested to issue a proclamation annually in commemoration of that day in 1920, on which the women of America were first given the right to vote, and that day in 1970, on which a nationwide demonstration for women’s rights took place.

August 25 is the 237th day of the year (238th in leap years) in the Gregorian calendar. There are 128 days remaining until the end of the year.

On this day in 1768, James Cook began his first voyage to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. This would be the first of three voyages that would be hailed as  heroic by the scientific community.

The routes of Captain James Cook’s voyages. The first voyage is shown in red, second voyage in green, and third voyage in blue. The route of Cook’s crew following his death is shown as a dashed blue line.

In 1766, the Royal Society hired (James) Cook to travel to the Pacific Ocean to observe and record the transit of Venus across the Sun. Cook was promoted to Lieutenant and named as commander of the expedition. The expedition sailed from England in 1768, rounded Cape Horn and continued westward across the Pacific to arrive at Tahiti  on 13 April 1769, where the observations were to be made. However, the result of the observations was not as conclusive or accurate as had been hoped. Cook later mapped the complete New Zealand coastline, making only some minor errors. He then sailed west, reaching the south-eastern coast of the Australian continent on 19 April 1770, and in doing so his expedition became the first recorded Europeans to have encountered its eastern coastline.

On 23 April he made his first recorded direct observation of indigenous Australians at Brush Island near Bawley Point, noting in his journal: “…and were so near the Shore as to distinguish several people upon the Sea beach they appear’d to be of a very dark or black Colour but whether this was the real colour of their skins or the C[l]othes they might have on I know not.” On 29 April Cook and crew made their first landfall on the mainland of the continent at a place now known as the Kurnell Peninsula, which he named Botany Bay after the unique specimens retrieved by the botanists Joseph Banks and Daniel Solander. It is here that James Cook made first contact with an Aboriginal tribe known as the Gweagal.

After his departure from Botany Bay he continued northwards, and a mishap occurred when Endeavour ran aground on a shoal of the Great Barrier Reef, on 11 June, and “nursed into a river mouth on 18 June 1770.” The ship was badly damaged and his voyage was delayed almost seven weeks while repairs were carried out on the beach (near the docks of modern Cooktown, at the mouth of the Endeavour River). Once repairs were complete the voyage continued, sailing through Torres Strait and on 22 August he landed on Possession Island, where he claimed the entire coastline he had just explored as British territory. He returned to England via Batavia (modern Jakarta, Indonesia), the Cape of Good Hope and the island of Saint Helena, arriving on 12 July 1771.

August 24 is the 236th day of the year (237th in leap years) in the Gregorian calendar. There are 129 days remaining until the end of the year.

On this day in 79 A.D., Mount Vesuvius erupted burying the cities of Pompeii and Herculaneum in nearly thirty feet of ash and pumice. The toxic gases killed at least 2200 people who remained in Pompeii after the evacuation.

After centuries of dormancy, Mount Vesuvius erupts in southern Italy, devastating the prosperous Roman cities of Pompeii and Herculaneum and killing thousands. The cities, buried under a thick layer of volcanic material and mud, were never rebuilt and largely forgotten in the course of history. In the 18th century, Pompeii and Herculaneum were rediscovered and excavated, providing an unprecedented archaeological record of the everyday life of an ancient civilization, startlingly preserved in sudden death.

At noon on August 24, 79 A.D., this pleasure and prosperity came to an end when the peak of Mount Vesuvius exploded, propelling a 10-mile mushroom cloud of ash and pumice into the stratosphere. For the next 12 hours, volcanic ash and a hail of pumice stones up to 3 inches in diameter showered Pompeii, forcing the city’s occupants to flee in terror. Some 2,000 people stayed in Pompeii, holed up in cellars or stone structures, hoping to wait out the eruption.

A westerly wind protected Herculaneum from the initial stage of the eruption, but then a giant cloud of hot ash and gas surged down the western flank of Vesuvius, engulfing the city and burning or asphyxiating all who remained. This lethal cloud was followed by a flood of volcanic mud and rock, burying the city.

The people who remained in Pompeii were killed on the morning of August 25 when a cloud of toxic gas poured into the city, suffocating all that remained. A flow of rock and ash followed, collapsing roofs and walls and burying the dead.

Plaster Citizens of Pompeii

Those that did not flee the city of Pompeii in August of 79 AD were doomed. Buried for 1700 years under 30 feet of mud and ash and reduced by the centuries to skeletons, they remained entombed until excavations in the early 1800s.

As excavators continued to uncovered human remains, they noticed that the skeletons were surrounded by voids in the compacted ash. By carefully pouring plaster of Paris into the spaces, the final poses, clothing, and faces of the last residents of Pompeii came to life.

n the only known eye witness account to the eruption, Pliny the Younger reported on his uncle’s ill-fated foray into the thick of the ash from Misenum, on the north end of the bay:

“. . .the buildings were now shaking with violent shocks, and seemed to be swaying to and fro as if they were torn from their foundations. Outside, on the other hand, there was the danger of failing pumice stones, even though these were light and porous; however, after comparing the risks they chose the latter. In my uncle’s case one reason outweighed the other, but for the others it was a choice of fears. As a protection against falling objects they put pillows on their heads tied down with cloths. ”

And then:

“You could hear the shrieks of women, the wailing of infants, and the shouting of men; some were calling their parents, others their children or their wives, trying to recognize them by their voices. People bewailed their own fate or that of their relatives, and there were some who prayed for death in their terror of dying. Many besought the aid of the gods, but still more imagined there were no gods left, and that the universe was plunged into eternal darkness for evermore.”

August 23 is the 235th day of the year (236th in leap years) in the Gregorian calendar. There are 130 days remaining until the end of the year.

On this day in 1902, pioneering cookbook author Fannie Farmer, who changed the way Americans prepare food by advocating the use of standardized measurements in recipes, opens Miss Farmer’s School of Cookery in Boston. In addition to teaching women about cooking, Farmer later educated medical professionals about the importance of proper nutrition for the sick.

Farmer was born March 23, 1857, and raised near Boston, Massachusetts. Her family believed in education for women and Farmer attended Medford High School; however, as a teenager she suffered a paralytic stroke that turned her into a homebound invalid for a period of years. As a result, she was unable to complete high school or attend college and her illness left her with a permanent limp. When she was in her early 30s, Farmer attended the Boston Cooking School. Founded in 1879, the school promoted a scientific approach to food preparation and trained women to become cooking teachers at a time when their employment opportunities were limited. Farmer graduated from the program in 1889 and in 1891 became the school’s principal. In 1896, she published her first cookbook, The Boston Cooking School Cookbook, which included a wide range of straightforward recipes along with information on cooking and sanitation techniques, household management and nutrition. Farmer’s book became a bestseller and revolutionized American cooking through its use of precise measurements, a novel culinary concept at the time.

Cookbook fame

Fannie published her most well-known work, The Boston Cooking-School Cook Book, in 1896. Her cookbook introduced the concept of using standardized measuring spoons and cups, as well as level measurement. A follow-up to an earlier version called Mrs. Lincoln’s Boston Cook Book, published by Mary J. Lincoln in 1884, the book under Farmer’s direction eventually contained 1,849 recipes, from milk toast to Zigaras à la Russe. Farmer also included essays on housekeeping, cleaning, canning and drying fruits and vegetables, and nutritional information.

The book’s publisher (Little, Brown & Company) did not predict good sales and limited the first edition to 3,000 copies, published at the author’s expense. The book was so popular in America, so thorough, and so comprehensive that cooks would refer to later editions simply as the “Fannie Farmer cookbook”, and it is still available in print over 100 years later.

Farmer provided scientific explanations of the chemical processes that occur in food during cooking, and also helped to standardize the system of measurements used in cooking in the USA. Before the Cookbook’s publication, other American recipes frequently called for amounts such as “a piece of butter the size of an egg” or “a teacup of milk.” Farmer’s systematic discussion of measurement – “A cupful is measured level … A tablespoonful is measured level. A teaspoonful is measured level.” – led to her being named “the mother of level measurements.”

I still have my copy.

August 22 is the 234th day of the year (235th in leap years) in the Gregorian calendar. There are 131 days remaining until the end of the year.

On this day in 1950, Althea Gibson became the first African American on the US Tennis Tour.

On this day in 1950, officials of the United States Lawn Tennis Association (USLTA) accept Althea Gibson into their annual championship at Forest Hills, New York, making her the first African-American player to compete in a U.S. national tennis competition.

Growing up in Harlem, the young Gibson was a natural athlete. She started playing tennis at the age of 14 and the very next year won her first tournament, the New York State girls’ championship, sponsored by the American Tennis Association (ATA), which was organized in 1916 by black players as an alternative to the exclusively white USLTA. After prominent doctors and tennis enthusiasts Hubert Eaton and R. Walter Johnson took Gibson under their wing, she won her first of what would be 10 straight ATA championships in 1947.

In 1949, Gibson attempted to gain entry into the USLTA’s National Grass Court Championships at Forest Hills, the precursor of the U.S. Open. When the USLTA failed to invite her to any qualifying tournaments, Alice Marble–a four-time winner at Forest Hills–wrote a letter on Gibson’s behalf to the editor of American Lawn Tennis magazine. Marble criticized the “bigotry” of her fellow USLTA members, suggesting that if Gibson posed a challenge to current tour players, “it’s only fair that they meet this challenge on the courts.” Gibson was subsequently invited to participate in a New Jersey qualifying event, where she earned a berth at Forest Hills.

Though she once brushed off comparisons to Jackie Robinson, the trailblazing black baseball player, Gibson has been credited with paving the way for African-American tennis champions such as Arthur Ashe and, more recently, Venus and Serena Williams. After a long illness, she died in 2003 at the age of 76.

Ms. Gibson became the first African American woman to join the Ladies Professional Golf Association  tour, in 1963, retiring in 1978.

On this day in 1959, Hawaii became our 50th state. Hawaii is the only U.S. state made up entirely of islands. It occupies most of an archipelago in the central Pacific Ocean, southwest of the continental United States, southeast of Japan, and northeast of Australia. Hawaii’s natural beauty, warm tropical climate, inviting waters and waves, and active volcanoes  make it a popular destination for tourists, surfers, biologists, and volcanologists alike. Due to its mid-Pacific location, Hawaii has many North American and Asian influences along with its own vibrant native culture. Hawaii has over a million permanent residents along with many visitors and U.S. military personnel. Its capital is Honolulu on the island of Oahu.

The state encompasses nearly the entire volcanic Hawaiian Island chain, which comprises hundreds of islands spread over 1,500 miles (2,400 km). At the southeastern end of the archipelago, the eight “main islands” are (from the northwest to southeast) Niihau, Kauai, Oahu, Molokai, Lanai, Kahoolawe, Maui, and Hawaii. The last is by far the largest and is often called “The Big Island” to avoid confusion with the state as a whole. The archipelago is physiographically and ethnologically part of the Polynesian subregion of Oceania.

The first known settlers of the Hawaiian Islands were Polynesian voyagers who arrived sometime in the eighth century. In the early 18th century, American traders came to Hawaii to exploit the islands’ sandalwood, which was much valued in China at the time. In the 1830s, the sugar industry was introduced to Hawaii and by the mid 19th century had become well established. American missionaries and planters brought about great changes in Hawaiian political, cultural, economic, and religious life. In 1840, a constitutional monarchy was established, stripping the Hawaiian monarch of much of his authority.

In 1893, a group of American expatriates and sugar planters supported by a division of U.S. Marines deposed Queen Liliuokalani, the last reigning monarch of Hawaii. One year later, the Republic of Hawaii was established as a U.S. protectorate with Hawaiian-born Sanford B. Dole as president. Many in Congress opposed the formal annexation of Hawaii, and it was not until 1898, following the use of the naval base at Pearl Harbor during the Spanish-American War, that Hawaii’s strategic importance became evident and formal annexation was approved. Two years later, Hawaii was organized into a formal U.S. territory. During World War II, Hawaii became firmly ensconced in the American national identity following the surprise Japanese attack on Pearl Harbor in December 1941.

Admission, or Statehood, Day is an official state holiday. It is the home state of President Barack Obama, the only President from that state and one of the most beautiful places I have ever visited. The pictures were the very hard to select. The second picture (above) is an aerial view of Diamond Head.

Diamond Head is a dormant volcanic cone on the island of Oahu. It is called Le’ahi by Hawaiians, most likely from lae ‘browridge, promontory’ plus ‘ahi ‘tuna’ because the shape of the ridgeline resembles the shape of a tuna’s dorsal fin. Its English name was given by British sailors in the 19th century, who mistook calcite crystals embedded in the rock for diamonds.

Then of course there are volcanoes at Hawaii Volcanoes National Park. The first picture on the left is the more famous of the volcanoes, Mauna Loa which is the largest volcano on Earth by volume and area and one of the five volcanoes in that form the islands.

August 20 is the 232nd day of the year (233rd in leap years) in the Gregorian calendar. There are 133 days remaining until the end of the year.

On this day in 1911, the first around-the-world telegram sent, 66 years before Voyager II launch

On this day in 1911, a dispatcher in the New York Times office sends the first telegram around the world via commercial service. Exactly 66 years later, the National Aeronautics and Space Administration (NASA) sends a different kind of message–a phonograph record containing information about Earth for extraterrestrial beings–shooting into space aboard the unmanned spacecraft Voyager II.

The Times decided to send its 1911 telegram in order to determine how fast a commercial message could be sent around the world by telegraph cable. The message, reading simply “This message sent around the world,” left the dispatch room on the 17th floor of the Times building in New York at 7 p.m. on August 20. After it traveled more than 28,000 miles, being relayed by 16 different operators, through San Francisco, the Philippines, Hong Kong, Saigon, Singapore, Bombay, Malta, Lisbon and the Azores–among other locations–the reply was received by the same operator 16.5 minutes later. It was the fastest time achieved by a commercial cablegram since the opening of the Pacific cable in 1900 by the Commercial Cable Company.

The Voyager 2 spacecraft is an unmanned interplanetary space probe launched on August 20, 1977. Both the Voyager 2 and the Voyager 1 space probes were designed, developed, and built at the Jet Propulsion Laboratory near Pasadena, California. Identical in form and instruments with its sister Voyager program craft Voyager 1, Voyager 2 was launched on a slower, more curved trajectory that allowed it to be kept in the plane of the Ecliptic (the plane of the Solar System) so that it could be sent on to Uranus and Neptune by means of utilizing gravity assists during its fly-by of Saturn in 1981 and of Uranus in 1986. Because of this chosen trajectory, Voyager 2 could not take a close-up look at the large Saturnian moon Titan as its sister space probe had. However, Voyager 2 did become the first and only spacecraft to make the spaceflight by Uranus and Neptune, and hence completing the Planetary Grand Tour. This is one that is made practical by a seldom-occurring geometric alignment of the outer planets (happening once every 175 years).

The Voyager 2 space probe has made the most productive unmanned space voyage so far, visiting all four of the Outer Planets and their systems of moons and rings, including the first two visits to previously unexplored Uranus and Neptune. Voyager 2 had two sensitive vidicon cameras and an assortment of other scientific instruments to make measurements in the ultraviolet, infrared, and radio wavelengths, as well as ones to measure subatomic particles in outer space, including cosmic rays. All of this was accomplished at a fraction of the amount of money that was later spent on more advanced and specialized space probes Galileo and Cassini-Huygens. Along with the earlier NASA Pioneer 10 and Pioneer 11, sister probe Voyager 1, and the more recent New Horizons, Voyager 2 is an interstellar probe in that all five of these are on one-way trajectories leaving the Solar System.
