Gabriel Baer (1919-1982) was a German-born Israeli orientalist, an expert on the social history of the 18th and 19th-century Middle East, notably Egypt but also the Ottoman Empire. Baer was born on 13 January 1919 in Berlin, Germany. He died in Jerusalem, Israel, on September 22, 1982.
A Trotskyist activist in his youth, he was a member of the German section of the Fourth International.
In 1933, he left for Mandatory Palestine.
He became a member of the Hugim Marxistiim (Marxist Circles), the youth group of a faction of Poale Zion, the labour Zionist movement but left it in 1937 with Trotskyist theoretician and activist Tony Cliff to found the Brit Kommunistim Mahapchanin (the Revolutionary Communist League), a section of the Fourth International in Palestine. In the late 1940s he left Palestine for Britain where he became a member of the Revolutionary Communist Party writing a number of articles in its paper Socialist Appeal. When the RCP collapsed he became a member of the Socialist Review group led by Tony Cliff who had joined him in Britain.
Under the byline "S. Munir," he wrote several articles on the political and social situation in the Middle East in the late 1940s and early 1950s.
