Samuel of Nehardea

Samuel of Nehardea or Samuel bar Abba, often simply called Samuel (Hebrew: שמואל) and occasionally Mar Samuel, was a Jewish Amora of the first generation; son of Abba bar Abba and head of the Yeshiva at Nehardea, Babylonia. He was a teacher of halakha, judge, physician, and astronomer. He was born about 165 CE at Nehardea, and died there in 254 CE. In the Talmud, Samuel is frequently associated with Abba Arikha ("Rav"), with whom he debated on many issues.
