Jerry S. Parr (September 16, 1930 – October 9, 2015) was an American Secret Service agent who is best known for his act of bravery in defending President Ronald Reagan during the attempt on the president's life on March 30, 1981, in Washington, D.C. Parr pushed Reagan into the presidential limousine and made the critical decision to divert the presidential motorcade to George Washington University Hospital instead of returning to the White House. He was honored for his actions that day with U.S. Congress commendations, and is widely credited with helping to save the president's life.
