Gerhard Herzberg (December 25, 1904–March 3, 1999) was a pioneering theoretical chemist. Herzberg's main work concerned atomic and molecular spectroscopy. He is well known for using these techniques to determine the structures of diatomic and polyatomic molecules, including free radicals difficult to investigate in any other way, and for the chemical analysis of astronomical objects.
