TIL that the first person in history we know the name of was an ordinary accountant named Kushim. He used his name to sign a clay tablet receipt for barley shipments, around 3100 BC.

The receipt says: “29,086 measures barley 37 months Kushim”. The most probable reading of this sentence is: “A total of 29,086 measures of barley were received over the course of 37 months. Signed, Kushim.”
