Early life
Alcorn was born on March 22, 1940, to Arletta Dixon Alcorn and George Edward Alcorn, Sr., in Indianapolis. They had another child, his younger brother Charles.
Education and academic career
Alcorn received a four-year academic scholarship to Occidental College in Los Angeles, where he graduated with a Bachelor of Science in physics. He received his degree with honors while earning eight letters in basketball and football. Alcorn earned a Master of Science in Nuclear Physics in 1963 from Howard University, after nine months of study. During the summers of 1962 and 1963, he worked as a research engineer for the Space Division of North American Rockwell. He was involved with the computer analysis of launch trajectories and orbital mechanics for Rockwell missiles, including the Titan I and II, the Saturn, and the Nova. After earning a PhD in Molecular and Atomic Physics from Howard University in 1967, he went on to hold teaching positions in electrical engineering at Howard University and the University of the District of Columbia, eventually rising to the rank of full professor.
Private industry work
After earning his PhD, Alcorn spent twelve years working in the private sector. He held positions as senior scientist at Philco-Ford, senior physicist at Perkin-Elmer, and advisory engineer at IBM.
Inventions
Alcorn's best-known invention is the X-ray spectrometer, which earned him the NASA–Goddard Space Flight Center award for Inventor of the Year in 1984. Other significant inventions concerned plasma etching for semiconductor devices. In 1999, Alcorn was honored with an award from Government Executive magazine for developing the Airborne LIDAR Topographic Mapping System (ALTMS) in partnership with the Houston Advanced Research Center.
In 2015, Alcorn was inducted into the National Inventors Hall of Fame for his invention of the X-ray spectrometer.
Personal life
Alcorn married his wife Marie DaVillier in 1969 and they have one son born in 1979. He later married Dorothy Green after the death of his first wife. Alcorn died on June 19, 2024.
