David Kossoff (November 24, 1919 – March 23, 2005) was an English actor. In 1954 he won a BAFTA for his appearance in The Young Lovers. Perhaps his best-known roles were Alf Larkin in The Larkins and Professor Kokintz in The Mouse that Roared (1959) and its sequel The Mouse on the Moon (1963). Because of the drug use of his son Paul, a rock musician, who subsequently died, he became an anti-drug campaigner.
