William Wilson Morgan

Born 3 Jan 1906; died 21 Jun 1994 at age 88. American astronomer who, in 1951,providedthe first evidence that the Milky Way Galaxy has spiral arms. He spent his entire career at the Yerkes Observatory, including three years as director. Eschewing theory, his research was devoted to morphology, the classification of objects by their form and structure. With Keenan and Kellman, he introduced stellar luminosity classes and the two-dimensional classification of stellar spectra strictly based on the spectra themselves. With Osterbrock and Sharpless he demonstrated the existence of spiral arms in the Galaxy using precise distances of O and B stars obtained from spectral classifications. Morgan invented the UBV system of magnitudes and colors.
