A contemporary of Rav's, Shmuel was the founding head of the academy in Nehardea.  It is hard to ascertain how and where he received his education. He was a native of Babylonia, and there is no record of his studying among the scholars of the Land of Israel.  He earned his livelihood as a physician/optometrist, and the high quality of his ointments earned him a "world wide" following in his day.
