Ira Sprague Bowen (December 21, 1898 – February 6, 1973) was an American astronomer. A graduate of Oberlin College and the California Institute of Technology, he taught physics at Caltech from 1921 to 1945.

In 1927 he discovered that Nebulium was not really a chemical element but instead doubly ionized oxygen.[1]
