Question
Who was the author of the Sefer Yereim?
Answer
R.Eliezer b.Shmuel of Metz, a student of Rabbeinu Tam, lived in the mid to late 1100's. The Yereim is his only known work; it was published in part in Venice in 1566, and in full in Vilna in 1892. Otherwise, almost nothing is known about his life or his career.
