Pamela Blackmon

physicist, inventor, and educator, was born in Indianapolis, Indiana, the eldest of two sons of Arletta (Dixon) Alcorn and George Alcorn, an auto mechanic. Little is known of his early life. George Alcorn Jr. earned a BA in Physics in 1962 from Occidental College in Pasadena, California, where he excelled both academically and athletically, earning eight letters in football and baseball. His educational pursuits took him next to Howard University, where he received a master's degree in Nuclear Physics after only nine months of study. During the summers of 1962 and 1963 Alcorn worked as a research engineer at the space division of North American Rockwell, where he computed trajectories and orbital mechanics for missiles, including the Titan I and II, the Saturn IV, and the Nova.

From 1965 to 1967 Alcorn researched negative ion formation with funded support from the National Aeronautics and Space ...

Philip Alexander

physicist, educator, and academic administrator, was born in Pocahontas, Virginia, the son of Harry P. Branson, a coal miner, and Gertrude Brown. In 1928, after several years at his local elementary school, Herman enrolled at Dunbar High School in Washington, D.C., one of the nation's preeminent black secondary schools. He was encouraged in this move by a young black physician, William Henry Welch, who practiced in Pocahontas and who rented lodgings from young Branson's grandmother.

At Dunbar, Branson was introduced to studies in Latin, advanced mathematics, and other disciplines to which he would not have been exposed in his local high school. After graduating as valedictorian in 1932 he enrolled at the University of Pittsburgh with a view to studying medicine partly because his great uncle had been trained as a physician there Branson completed the premedical program in two years and still found time ...

Olivia A. Scriven

feminist scholar, historian, physicist, engineer, and advocate for minorities and women in science, was born in Atlanta, Georgia, the oldest of two girls of William Emmett Hammonds, a postal worker, and Evelyn Marie Hammonds, a reading specialist and elementary school teacher. At age nine, Hammonds's father gave his daughter a chemistry set. For Hammonds, the chemistry set, along with later gifts of a microscope, and building sets, sparked an interest in science that would be encouraged by both parents. The events also set her on a path that would force her to think more critically about her own identity and the struggles and contributions of blacks and women in science.

Growing up in Atlanta, Hammonds attended all-black public elementary schools. This would change in 1967 when as a fourteen year old ninth grade student she was bused to a predominately white school ...

Jeffrey R. Yost

physicist, was born in Evergreen, Alabama. His father, Nelson Henry, and his mother, Mattye McDaniel Henry, were public school teachers who had graduated from Tuskegee Institute. Education was deeply valued in the Henry household, and Warren's parents brought him along to the classroom and encouraged him to study long hours during his adolescent and teenage years. He became interested in science early in life, though he did not have the opportunity to take any science courses until his senior year, when he transferred to Alabama State Normal, a school in Montgomery that concentrated on preparing future elementary school teachers. Following in his parents' footsteps, Henry worked his way through Tuskegee Institute as a night watchman and at a pharmacy, receiving a bachelor of science degree in 1931 majoring in mathematics English and French He also completed course work in chemistry and physics and worked summers on ...

Georgia L. Irby-Massie

Greek polymath who worked in mathematics, astronomy, and mechanics. He is especially famous for descriptions of automata (air-, water-, and steam-powered mechanical devices) and steam-powered aeolipiles. “Hero’s engine,” deriving from Ctesibius of Alexandria’s design (290250 bce), is the first device to transform steam into rotary motion. The aeolipile consists of a hollow sphere attached by pipes to an enclosed water-filled cauldron. When the cauldron is heated, the sphere spins on a pivot as it releases steam (Pneumatics 50).

Hero’s much disputed floruit was pinpointed by Neugebauer (1975, 846), who noted that Hero used eyewitness evidence of a lunar eclipse of 62 ce, visible from both Rome and Alexandria, to calculate the distance between those two cities (Dioptra 35). Making no use of Ptolemy of Alexandria (127after 146 ce Hero likely predated Ptolemy Neugebauer Very little is known of Hero s life His mathematical corpus ...

Historian, editor, and political activist born on 10 December 1921 near Johannesburg, the child of Latvian Jews. Hirson was educated at Hebrew school in Johannesburg, and studied mathematics at the University of Witwatersrand, where he later worked as a physicist. In 1940 he joined the left‐wing Hashomer Hatzair, subsequently becoming a member of various Trotskyist groups. Between 1944 and 1946 he was a political organizer for the Workers' International League.

Hirson participated in setting up black trade unions, in extremely difficult conditions created by the Suppression of Communism Act. He became involved in the Non‐European Unity Movement, and in the late 1950s joined the Congress of Democrats, the white arm of the ANC‐led Congress Alliance.

After the Sharpeville massacre in 1960 Hirson and his colleagues highly critical of the Congress Alliance s leadership and policies organized the National Committee for Liberation which advocated sabotage as a substitute for peaceful ...

physicist, chair of the U.S. Nuclear Regulatory Commission, and educator was born in Washington, D.C., the second of four children to George Jackson, a post office employee, and Beatrice Cosby, a social worker. In elementary school Shirley was bused from the Jacksons' largely white neighborhood in northwest Washington to a black school across town. After the 1954Brown v. Board of Education desegregation ruling and several years of “white flight” transformed the area into a predominantly black neighborhood, she attended the local Roosevelt High School, where she participated in an accelerated program in math and science. Jackson took college-level classes in her senior year, after completing the high school curriculum early, and she graduated as valedictorian in 1964 As I was growing up she recalled I became fascinated with the notion that the physical world around me was a world of secrets and that science as ...

Pamela C. Edwards

physicist, space scientist, and mathematician, was born in White Sulphur Springs, West Virginia. Johnson started attending the local elementary school, but in the 1920s and 1930s, the public school system in White Sulphur Springs did not provide educational opportunities for black children beyond the eighth grade. In a 1997 interview with the Richmond Post-Dispatch, Johnson recalled that her parents were determined to give their children every educational opportunity and moved to Institute, West Virginia—120 miles away—in September of every year so that Johnson and her siblings could attend school. Johnson attended West Virginia State College, where she earned a BS in French and Mathematics and explored her interests in physics. Graduating summa cum laude in 1937, she taught high school and elementary school in southwest Virginia before going to work for NASA.

In 1953 Johnson joined NASA s Langley Research Center in Hampton Virginia ...
