Abraham Wasserstein (born Frankfurt am Main, 1921, died Jerusalem, 1995) taught at the universities of Glasgow and Leicester before taking up a chair in Greek at the Hebrew University of Jerusalem, in 1969, where he stayed until his death in 1995. He had special interests in Greek literature and science, and wrote widely in these fields. His publications include an edition of the medieval Hebrew translation of Galen's commentary on Hippocrates' Airs, Waters and Places (lost in the original Greek). The present book was begun by him and left incomplete at his death.
