There is, then, the possibility that this Af bond is symmetric, although Douglass was unable to determine its symmetry from his x-ray data.

Dr. Douglass was kind enough to lend us about 5 grams of his material.

The x-ray diffraction pattern of the material, taken with CuK**ya radiation, indicated the presence of no extra lines and was in good agreement with the pattern of Douglass.

Frederick Douglass once observed of Lincoln: " In his company, I was never reminded of my humble origin, or of my unpopular color ".

According to Douglass, smallpox inoculation was " a medical experiment of consequence ," one not to be undertaken lightly.

Frederick Douglass ( born Frederick Augustus Washington Bailey, c. February 1818 – February 20, 1895 ) was an American social reformer, orator, writer and statesman.

Douglass was a firm believer in the equality of all people, whether black, female, Native American, or recent immigrant, famously quoted as saying, " I would unite with anybody to do right and with nobody to do wrong.

Frederick Augustus Washington Bailey, who later became known as Frederick Douglass, was born a slave in Talbot County, Maryland, between Hillsboro and Cordova, probably in his grandmother's shack east of Tappers Corner () and west of Tuckahoe Creek.

His mother died when Douglass was about 10.

At age seven, Douglass was separated from his grandmother and moved to the Wye House plantation, where Aaron Anthony worked as overseer.

When Anthony died, Douglass was given to Lucretia Auld, wife of Thomas Auld.

When Douglass was about twelve years old, Hugh Auld's wife Sophia started teaching him the alphabet despite the fact that it was against the law to teach slaves to read.

" As Douglass began to read newspapers, political materials, and books of every description, he was exposed to a new realm of thought that led him to question and condemn the institution of slavery.

When Douglass was hired out to William Freeland, he taught other slaves on the plantation to read the New Testament at a weekly Sunday school.

The sixteen-year-old Douglass was nearly broken psychologically by his ordeal under Covey, but he finally rebelled against the beatings and fought back.

Douglass first tried to escape from Freeland, who had hired him out from his owner Colonel Lloyd, but was unsuccessful.

At one of these meetings, Douglass was unexpectedly invited to speak.

Douglass was inspired by Garrison and later stated that " no face and form ever impressed me with such sentiments the hatred of slavery as did those of William Lloyd Garrison.

" Garrison was likewise impressed with Douglass and wrote of him in The Liberator.

Douglass set sail on the Cambria for Liverpool on August 16, 1845, and arrived in Ireland as the Irish Potato Famine was beginning.

His draw was such that some facilities were " crowded to suffocation "; an example was his hugely popular London Reception Speech, which Douglass delivered at Alexander Fletcher's Finsbury Chapel in May 1846.

Douglass remarked that in England he was treated not " as a color, but as a man.

Douglass prepared his sample of Af by thermal decomposition of aqueous chromic acid at 300 - 325-degrees-C.

In later years, Douglass credited The Columbian Orator, which he discovered at about age twelve, with clarifying and defining his views on freedom and human rights.

Several days later, Douglass delivered his first speech at the Massachusetts Anti-Slavery Society's annual convention in Nantucket.

Douglass later shared a stage at a speaking engagement in Harpers Ferry with Andrew Hunter, the prosecutor who successfully convicted Brown.

His son Frederick Douglass Jr. also served as a recruiter and his other son, Lewis Douglass, fought for the 54th Massachusetts Regiment at the Battle of Fort Wagner.

Douglass and Anna had five children: Rosetta Douglass, Lewis Henry Douglass, Frederick Douglass, Jr., Charles Remond Douglass, and Annie Douglass ( died at the age of ten ).

In 1888, Douglass spoke at Claflin College, a black college in Orangeburg, South Carolina and the oldest such institution in the state.

Shortly after he returned home, Frederick Douglass died of a massive heart attack or stroke in Washington, D. C. His funeral was held at the Metropolitan African Methodist Episcopal Church where thousands passed by his coffin paying tribute.

Douglass published three versions of his autobiography during his lifetime ( and revised the third of these ), each time expanding on the previous one.

After the raid, Douglass fled for a time to Canada, fearing guilt by association and arrest as a co-conspirator.

By the time of the Civil War, Douglass was one of the most famous black men in the country, known for his orations on the condition of the black race and on other issues such as women's rights.

In 1869, long-time friends Frederick Douglass and Susan B. Anthony found themselves, for the first time, on opposing sides of a debate.

In his third autobiography, Douglass wrote: " On one occasion I had eleven fugitives at the same time under my roof, and it was necessary for them to remain with me until I could collect sufficient money to get them on to Canada.

Dendrochronology ( word derived from Greek, dendron, " tree limb ";, khronos, " time "; and ,-logia ) was developed during the first half of the 20th century originally by the astronomer A. E. Douglass, the founder of the Laboratory of Tree-Ring Research at the University of Arizona.

* Frederick Douglass ( 1818 – 95 ), lived in Long Branch for a short period of time until his home burnt down.

Douglas ( at one time spelled Douglass ) is a town in Marquette County, Wisconsin, United States.

By 1960, nearly every prime time show in America was sweetened by Douglass.

When it came time to " lay in the laughs ", the producer would direct Douglass where and when to insert the type of laugh requested.

Douglass used a keyboard to select the style, gender and age of the laugh as well as a foot pedal to time the length of the reaction.

By 1969, nearly all cartoon shows produced — both for the Saturday morning fare as well as prime time — followed Filmation's lead and included Douglass ’ s laugh track, including The Pink Panther Show, Scooby-Doo, Where Are You ?, Harlem Globetrotters and Josie and the Pussycats.

In 1886 he was appointed by President Grover Cleveland as Recorder of Deeds for the District of Columbia, the highest federal position filled by black men at the time ; two other prominent men of color of that era, Fredrick Douglass ( 1881 – 1886 ) and Senator Blanche Kelso Bruce ( 1891 – 1893 ), served before and after Trotter.

For a short time he became a noted abolitionist speaker and later a showman, but later lost the support of the abolitionist community, notably Frederick Douglass, who wished Brown had kept quiet about his escape so that more slaves could have escaped using similar means.

During this time it also released five of the cast albums from the Music Theatre of Lincoln Center revivals, The Merry Widow with Patricia Munsel, Show Boat with Barbara Cook, Constance Towers, Stephen Douglass, David Wayne and William Warfield, Kismet with Alfred Drake, Annie Get Your Gun with Ethel Merman, Carousel with John Raitt and The King and I with Rise Stevens and Darren McGavin.

While under the control of Mr. Covey, Douglass is a field hand and has an especially hard time at the tasks required of him.

The publication of Narrative of the Life of Frederick Douglass opened several doors, not only for Douglass ' ambitious work, but also for the anti-slavery movement of that time.

One of his biggest critics, A. C. C. Thompson, was a neighbor of Thomas Auld, who was the master of Douglass for some time.

The League was backed by many prominent activists of the time, such as Edward Douglass White, who argued against it in the Louisiana Supreme Court and Anthony Comstock.

Abolitionist and former slave Frederick Douglass provided Stanton's son, Theodore, this memory of the first time he heard Henry B. Stanton speak in public:

Lewis ' son, Lewis Hallam, Jr., eighteen at the time of the American Company's first tour, took leading roles alongside Douglass.

This was done to avoid paying large fees to Charley Douglass, who edited laugh tracks onto the majority of network television shows at the time.

With support from many of the leaders of his time such as Frederick Douglass and William Lloyd Garrison, Williams founded The Commoner, a monthly journal, in Washington, D. C.
