That’s Ronald Reagan, just before being shot by John Hinckley outside the Washington Hilton Hotel on March 30, 1981. The man in the white raincoat is Secret Service agent Jerry Parr; after the shooting, it was Parr who pushed Reagan into a limousine, noticed he was bleeding, and directed the driver to take them to a hospital, probably saving Reagan’s life.

Parr had been inspired to pursue his career by the 1939 film The Code of the Secret Service, in which dashing agent “Brass” Bancroft survives a shooting in Mexico. Bancroft was played by a 28-year-old Ronald Reagan.

(Thanks, Colin.)
