Lachmann recorded musicians in North Africa and in Palestine on wax cylinders mostly before he established his Center for Oriental Music. Robert Lachmann arrived in Palestine in April 1935 after he was dismissed from his position at the Berlin National Library.
He came at the invitation of J. L. Magnes, president of the Hebrew University. Until his last day he recorded Arabic music, Jewish oriental traditions and the music of the Samaritans. Lachmann also presented lectures for the Palestine Broadcasting Service (PBS).
