Lewis Boss

Lewis Boss ( born October 26, 1846 in Providence, Rhode Iceland, † October 5, 1912 in Albany, New York ) was an American astronomer. His son was the astronomer Benjamin Boss.

In 1876 he became director of the Dudley Observatory in Schenectady, New York. In 1882 he led an expedition to Chile to observe the transit of Venus.

Lewis Boss is known for its cataloging of positions and proper motions of stars. In 1910 he published the Preliminary General Catalogue of 6188 Stars for the Epoch 1900, a compilation of stellar proper motions. This catalog was continued after his death.

His most important discovery was the calculation of the convergent point of the Hyades star cluster.

Boss in 1905 was awarded the Gold Medal of the Royal Astronomical Society. The lunar crater boss is named after him.
