Emmett attended a one-room school for several years, but he graduated from a segregated high school that was part of the Phoenix, Arizona district.He was the bottom graduate in his 25-student senior class.
He joined the army
In 1942, Chappelle became part of the army and was assigned to a special unit that involved engineering.While taking part in this he was wounded in action twice, and in 1946, attended Phoenix College and studied electrical engineering.
He graduated for College
In 1950 Emmett Chappelle graduated with a degree in Biology. Four years later Chappelle earned a master’s degree at University of Washington, Seattle. He studied and worked as a research associate at Stanford University in California.
He served as a Biochemisty
From 1950 until 1953, he served as an instructor of biochemistry at Meharry Medical college in Nashville, Tennessee.
Then from 1955 until 1959 he was an research associate at Stanford University. Going back to 1958 Chappelle joined the advanced studies in Baltimore, which was famous for designing airplanes and spacecrafts. While being a part of this institute Chappelle discovered that one-celled plants like algae, can be transported easily, and can convert carbon dioxide to oxygen.
He made an discovery
With this discovery in mind, this led to create a safe oxygen supply for astronauts. In 1963, Emmett Chappelle went to work at Hazelton laboratories as a biochemist. After a couple of years in 1966, he joined the national Aeronautics and Space Administration as a research chemist. In 2001 Chappelle retired from the NASA.
In 1966, Chappelle joined the National Aeronautics and Space Administration (NASA) as a part of the Goddard Space Flight Center. Chappelle’s research has focused in the area of luminescence, which is light without heat. He has been involved in a number of projects, including the Viking space craft.
Chappelle retired from NASA. He has received fourteen U.S. patents, produced more than thirty-five peer-reviewed scientific or technical publications, nearly fifty conference papers, and co-authored or edited numerous publications.
He got Honored
Chappelle has been honored as one of the top 100 African American scientist and engineers of the 20th century. He has received an Exceptional Scientific Achievement Medal from NASA for his work. Chappelle was inducted into the National Inventors Hall of Fame in 2007.
He is alive and well
