NEW YORK—Cecil Stoughton, the White House photographer who shot the iconic image of Lyndon Johnson taking the oath of office after John F. Kennedy was assassinated, has died. He was 88.

Stoughton died Monday evening at his at his home on Merritt Island, Fla., his son Jamie Stoughton said.

The photo he took of the swearing-in ceremony aboard Air Force One, Johnson with his hand raised and a stunned Jacqueline Kennedy looking on, became the most famous in his five years, 1961-65, as White House photographer.

“Cecil Stoughton’s photos helped to create the aura that later came to be called Camelot,” said Bobbi Baker Burrows, director of photography at Life magazine and co-author of the National Geographic Society’s 2006 publication, “The Kennedy Mystique.”

“In the confusion that followed the assassination, his (swearing-in) photograph told the world that there was a new president, and the country that it was safe,” Burrows said.

Stoughton was an Army captain in 1961 when picked by Kennedy’s military aide, Maj. Gen. Chester Clifton, to photograph daily events at the White House. He was the first official White House photographer, a position that has since become standard for presidents.

During those years he became close to the Kennedy family.

Accompanying Kennedy to Dallas on Nov. 22, 1963, Stoughton was in the fifth car in the motorcade and heard the shots that fatally wounded the president. He was at Parkland Hospital, where Kennedy died, when he learned he had to go photograph the swearing-in before Air Force One left for Washington D.C.

“He took about 20 pictures but the first one almost didn’t happen because his Hasselblad—the Rolls-Royce of cameras—malfunctioned,” his son said.

“He was under tremendous pressure. If his camera had failed, who knows what would have happened? It was the only proof that Johnson had been sworn in.”

In all, he said, his father shot about 12,000 negatives during the Kennedy years, which are now archived at the John F. Kennedy Presidential Library and Museum in Boston.
