Roger Donoghue (November 20, 1930 – August 20, 2006) was a prizefighter who taught Marlon Brando how to box for his role in the 1954 movie On the Waterfront.
Donoghue gave his winnings from that match to Flores' family, and New York instituted the requirement that boxers take a 30-day break from the ring after being knocked out.
A friend of Donoghue's, writer Budd Schulberg, once asked him how far he might have gone as a fighter if not for the Flores incident.
Director Elia Kazan agreed to pay Donoghue $75 a day to coach Brando in boxing.
Donoghue died in Greenport, New York of complications from Alzheimer's disease wife, Faye Moore a famous equestrian artist.
