Puzo 1920–1999 · Coppola b. 1939 · screenwriters, The Godfather Part II (1974)
Mario Puzo (15 October 1920 – 2 July 1999) wrote the 1969 novel The Godfather and shared the screenplay credit on Coppola’s first two Godfather films; Francis Ford Coppola (b. 7 April 1939) directed them and shared that credit. The pair won the Academy Award for Best Adapted Screenplay for both The Godfather and The Godfather Part II. Which of the two typed this particular sentence is not documented anywhere — the writing credit is joint, and neither man has publicly claimed the line.
