Why Is Ira Sprague Bowen Influential?
(Suggest an Edit or Addition)According to Wikipedia, Ira Sprague Bowen was an American physicist and astronomer. In 1927 he discovered that nebulium was not really a chemical element but instead doubly ionized oxygen. Life and work Bowen was born in Seneca Falls, New York in 1898 to Philinda Sprague and James Bowen. Due to frequent moves of his family he was home schooled until his father died in 1908. From that point on he attended Houghton College where his mother worked as teacher. After graduation from high school in 1915 Bowen stayed at the junior college of Houghton College, and later joined Oberlin College from which he graduated in 1919. During his time at Oberlin, Bowen did some research on the properties of steel for the scientist Robert Hadfield. Their results were published in 1921.
