Civil Rights Leader. He was a prominent African-American lawyer, Dean of Howard University Law School, and NAACP Litigation Director who played a significant role in dismantling the Jim Crow laws, which earned him the title "The Man Who Killed Jim Crow". He is also well known for having trained future Supreme Court Justice Thurgood Marshall.
Interesting, he remembered the time before Jim Crow. The Delaney sisters wrote about the transition to Jim Crow years in their book. Just like Confederate monuments, Jim Crow rose long after the Civil War ended.

Katherine Johnson was a 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 33-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. She was known as a "human computer" for her tremendous mathematical capability and ability to work with space trajectories with such little technology and recognition at the time.

Charles Richard Drew (June 3, 1904 – April 1, 1950) was an American surgeon and medical researcher. He researched in the field of blood transfusions, developing improved techniques for blood storage, and applied his expert knowledge to developing large-scale blood banks early in World War II. This allowed medics to save thousands of Allied forces' lives during the war.[1] As the most prominent African American in the field, Drew protested against the practice of racial segregation in the donation of blood, as it lacked scientific foundation, and resigned his position with the American Red Cross, which maintained the policy until 1950.
