About Gerald Hawkins

Gerald Stanley Hawkins was a British-born American astronomer and author noted for his work in the field of archaeoastronomy. A professor and chair of the astronomy department at Boston University in the United States, he published in 1963 an analysis of Stonehenge in which he was the first to propose that it was an ancient astronomical observatory used to predict movements of the sun and moon, and that it was used as a computer. Archaeologists and other scholars have since demonstrated such sophisticated, complex planning and construction at other prehistoric earthwork sites, such as Cahokia in the U.S.
