William Hammond Wright
After graduating in 1893 from the University of California, he became Assistant Astronomer at Lick Observatory. From 1903 to 1906 he worked on establishing the "Southern station" of the observatory at Cerro San Cristobal near Santiago de Chile. It only took him 6 months to start with observations from this new site, and he recorded a large series of radial velocity measurements of stars in the southern sky. In 1908 he was promoted to Astronomer. From 1918 to 1919 he was stationed at Aberdeen Proving Ground working for the ordinance section of the United States Army. He then returned to the Lick Observatory and worked there until his retirement.
He is most famous for his work on radial velocity of stars in our galaxy, and his work with a spectrograph he designed himself. He obtained spectra of novas and nebulas. In 1924 he made photographic observations of Mars in multiple wave lengths. From these pictures he concluded that its atmosphere was about 60 miles (100 km) deep.
