Maimonides was a tenth century Jewish philosopher. Heavily influenced by the Arabic philosophers of the age, he was prominent in promoting the idea that God is indivisible and incorporeal. Although he certainly wasn't the first Jewish thinker to say that God doesn't have a physical body, he very strongly imposed it as an article of faith in the Jewish community, claiming that anyone who said that God had a body was an infidel.
