From a New York Times obit by Sam Roberts headlined “Dr. Dennis O’Leary, Voice of Calm After Reagan Was Shot, Dies at 85”:

Dr. Dennis O’Leary, the Washington hospital administrator whose edifying medical briefings delivered in his calm baritone reassured a world shocked by the attempted assassination of President Ronald Reagan in 1981, died in Kansas City, Mo.

For nearly two weeks following the ambush of Mr. Reagan, who was shot on March 30 by John W. Hinckley Jr. while leaving the Washington Hilton Hotel, Dr. O’Leary was the even-keeled spokesman who updated the news media on the president’s prognosis and the condition of others wounded in the attack.
