Hale graduated from the Massachusetts Institute of Technology in 1890 and became a professor at the University of Chicago in 1897. He was director of the Yerkes Observatory from 1895 to 1905 and of the Mount Wilson Observatory from 1904 to 1923. Hale’s principal works are devoted to solar and stellar research. He is known for his use of the spectrohelioscope, the spectroheli-ograph, and the tower telescope to make solar observations. He predicted and verified with observational data the existence of magnetic fiel-s in sunspots. Hale was the founder and first editor of the Astrophysical Journal (1895).
