Emmett Chappelle Inventor

Emmett W. Chappelle (born 25 October 1925) is an African American scientist who made valuable contributions in several fields: medicine, philanthropy, food science, and astrochemistry. From 1950 to 1955 he served as an instructor of biochemistry at Meharry Medical College in Nashville, Tennessee. From 1955 to 1959, he was a research associate at Stanford University. In 1958 Chappelle joined the Research Institute in Baltimore, a division of the Martin Marietta Corporation which was famous for designing airplanes and spacecraft. There, Chappelle discovered that even one-celled plants such as algae, which are lightweight and can be transported easily, can convert carbon dioxide to oxygen. This discovery helped to create a safe food supply for astronauts. Chappelle went to work at Hazelton Laboratories in 1963 as a biochemist. In 1966, he joined the National Aeronautics and Space Administration at the Goddard Space Flight Center in Greenbelt, Maryland, as a research chemist, and later became a remote sensing scientist, studying natural systems to improve environmental management. Chappelle retired from NASA in 2001.
