(Suggest an Edit or Addition)

According to Wikipedia, Olin Chaddock Wilson was an American astronomer best known for his work as a stellar spectroscopist. Born in San Francisco, California as the son of a lawyer, Wilson showed an interest in physics at an early age. He studied astronomy and physics at the University of California, Berkeley and wrote his first scientific paper in 1932 on the subject of the speed of light. He received his PhD from the California Institute of Technology in 1934.
