It is not known for sure who is the author (writer) of 1,2 Kings. Jewish tradition says that Jeremiah wrote 1 and 2 Kings, but people do not usually think so today. Whoever the author was, he knew the book of Deuteronomy, like many of Israel's prophets. He also used lots of sources, like "the books of the annals of Solomon" (11:41, NIV), "the book of the annals of the kings of Israel" (14:19 NIV), and "the book of the annals of the kings of Judah" (14:29 NIV)". Probably other sources were used, like those inside Chronicles).
