Samuel taught the Torah, the Book of Joshua, and the Israelite Oral Law. He also wrote (and taught) the Book of Judges, the Book of Ruth, and the Book of 1 Samuel.
More about Samuel:
1) He served as Judge (1 Samuel 7:15) and leader. Each year, he traveled in order to teach and serve as Judge (1 Samuel 7:16) in the various places.
2) He guided the people when they requested that a king be appointed (1 Samuel ch.8); and he appointed Saul and later King David, at the word of God (1 Samuel ch.9-10 and ch.16). (See: Choosing a king)
3) He wrote the Books of Ruth and Judges (Talmud, Bava Batra 14b) and the Book of Samuel (until the verse concerning his death; it was completed by another prophet. Talmud, ibid).
4) He led the people in a great movement of repentance (1 Samuel ch.7).
5) Until his time, prophecy had been relatively rare (1 Samuel 3:1). Starting with his leadership, the phenomenon of the "sons (disciples) of the Prophets" (2 Kings 2:3) became a regular institution, and very many people reached the various levels of prophecy (Talmud, Megillah 14a) (though only fifty-five prophets were commanded to record their words for posterity. Ibid).
