William Sheehan

William Sheehan is an American astronomer, psychiatrist, and astronomical historian known for his detailed works on the history of astronomy and planetary observation. His extensive writing career includes authoritative books on Mars, Neptune, and the search for Planet X. As a leading historian of astronomy, Sheehan has documented the development of planetary observation techniques and the major figures who advanced our understanding of the solar system. His biographical works include studies of Edward Emerson Barnard and Percival Lowell, combining rigorous historical research with scientific expertise. Sheehan's dual background in astronomy and psychiatry has informed his unique analytical approach to astronomical history, particularly in examining the personalities and motivations of historical astronomers. He has served as a contributing editor to Sky & Telescope magazine and has been awarded the American Astronomical Society's Donald E. Osterbrock Book Prize for Historical Astronomy. The asteroid 16037 Sheehan was named in his honor in recognition of his contributions to astronomical history and science writing. His work continues to serve as an important reference for both amateur astronomers and professional historians of science.
