Samson ben Isaac of Chinon (c. 1260 – c. 1330) (Hebrew: שמשון מקינון) was a French Talmudist who lived at Chinon. In Talmudic literature he is generally called after his native place, Chinon (Hebr. קינון), and sometimes by the abbreviation MaHaRShaḲ. He was a contemporary of Peretz Kohen Gerondi, who declared Samson to be the greatest rabbinical authority of his time. The name of his brother was Matatia. Source: Wikipedia (en)
