He was awarded his Ph.D. from Harvard University in 1943, at the age of 23, with a dissertation on An Investigation of the Shock Wave Produced by an Explosion in Air.

Hornig assumed office on January 24, 1964, but did not get along with the new president, Lyndon Baines Johnson, who had poor relationships with many scientists.
