Gerald James Toomer (born 23 November 1934) is a historian of astronomy and mathematics who has written numerous books and papers on ancient Greek and medieval Islamic astronomy. In particular, he translated Ptolemy's Almagest into English.

Formerly a fellow of Corpus Christi College, Cambridge University, he moved to Brown University as a special student in 1959 to study "the history of mathematics in antiquity and the transmission of these systems through Arabic into medieval Europe."[1] He joined the History of Mathematics department in 1963, became an associate professor in 1965, and was the chairman from 1980 to 1986.[2][3]
