According to passages 14b and 15a of the Bava Basra tractate of the Talmud, the book was written by Samuel up until 1 Samuel 25, which notes the death of Samuel, and the remainder by the prophets Gad and Nathan. Critical scholars from the 19th century onward have rejected this idea. However, even prior to this, the medieval Jewish commentator Isaac Abarbanel noted that the presence of anachronistic expressions (such as "to this day" and "in the past") indicated that there must have been a later editor such as Jeremiah or Ezra. Martin Noth in 1943 theorized that Samuel was composed by a single author as part of a history of Israel: the Deuteronomistic history (made up of Deuteronomy, Joshua, Judges, Samuel and Kings). Although Noth's belief that the entire history was composed by a single individual has been largely abandoned, his theory in its broad outline has been adopted by most scholars.
