George Ellery Hale (1868-1938) founded the Observatory in 1904 and directed it until his retirement in 1923. In the photograph above, taken around 1905, he is working in his office in the Monastery, the dormitory for astronomers on the mountain.
Hale's most acclaimed scientific work was his demonstration that sunspots have strong magnetic fields. Hale's Polarity Law shows evidence of the existence of a well-organized large-scale magnetic field in the solar interior that cyclically changes polarity on average every 11 years.
