His father was a lumber trader, and his cousin was future chess grandmaster Aron Nimzowitsch. In 1919, he studied chemistry and philosophy at the University of Berlin. After completing his doctorate in 1924, he went on to study biochemistry and medicine, receiving an MD in 1934 from the University of Basel.
He migrated to Israel in 1935 and settled in Jerusalem. Leibowitz was married to Greta, with whom he had six children.
