Didn't he kill himself around the same time Robin Williams did?
I admire Dr. Martin Luther King and Nelson Mandela. I know Mandela isn't an African American but he's still an important figure in Black history.
Creola Katherine Johnson (née Coleman; August 26, 1918 – February 24, 2020) was an American mathematician whose calculations of orbital mechanics as a NASA employee were critical to the success of the first and subsequent U.S. crewed spaceflights. During her 35-year career at NASA and its predecessor, she earned a reputation for mastering complex manual calculations and helped pioneer the use of computers to perform the tasks. The space agency noted her "historical role as one of the first African-American women to work as a NASA scientist".
Johnson's work included calculating trajectories, launch windows, and emergency return paths for Project Mercury spaceflights, including those for astronauts Alan Shepard, the first American in space, and John Glenn, the first American in orbit, and rendezvous paths for the Apollo Lunar Module and command module on flights to the Moon. Her calculations were also essential to the beginning of the Space Shuttle program, and she worked on plans for a mission to Mars.
In 2015, President Barack Obama awarded Johnson the Presidential Medal of Freedom. In 2016, she was presented with the Silver Snoopy Award by NASA astronaut Leland D. Melvin and a NASA Group Achievement Award. She was portrayed by Taraji P. Henson as a lead character in the 2016 film Hidden Figures. In 2019, Johnson was awarded the Congressional Gold Medal.
Vivien Theodore Thomas (August 29, 1910 – November 26, 1985) was an American laboratory supervisor who developed a procedure used to treat blue baby syndrome (now known as cyanotic heart disease) in the 1940s. He was the assistant to surgeon Alfred Blalock in Blalock's experimental animal laboratory at Vanderbilt University in Nashville, Tennessee, and later at the Johns Hopkins University in Baltimore, Maryland. He served as supervisor of the surgical laboratories at Johns Hopkins for 35 years. In 1976 Hopkins awarded him an honorary doctorate and named him an instructor of surgery for the Johns Hopkins School of Medicine. Without any education past high school, Thomas rose above poverty and racism to become a cardiac surgery pioneer and a teacher of operative techniques to many of the country's most prominent surgeons.
A PBS documentary Partners of the Heart, was broadcast in 2003 on PBS's American Experience. In the 2004 HBO movie, Something the Lord Made, Vivien Thomas was portrayed by Mos Def.
