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 ...

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 ...

Leila Kamali

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 ...

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 ...
