Galitzen was a native of southern California, and won acclaim both for his individual diving and as a tandem diver with his brother John. He won two medals in diving at Amsterdam in 1928 as Michael Galitzen. In 1931 his coach suggested that the brothers use Americanized stage names — "Mickey Riley" and "Johnny Riley." He won gold and silver medals in Los Angeles in 1932 under that name. After the Olympics, he worked as a film editor, and he and John appeared frequently in diving shows. He was found dead in his Hollywood apartment in 1959; the death was attributed to natural causes.

Galitzen was inducted into the International Swimming Hall of Fame in 1977.
