John Hermes Secondari (November 1, 1919 – February 8, 1975) was an American author and television producer. Secondari's 1952 novel Coins in the Fountain was made into the 1954 Academy Award-winning film Three Coins in the Fountain, and then in 1964, to his disappointment, remade as the Twentieth Century-Fox film The Pleasure Seekers. He went on to write plays for Playhouse 90 and was the founding Washington Bureau Chief and White House Correspondent for the ABC Television Network. In 1963, he produced the Emmy-nominated and Peabody Award-winning ABC television series Saga of Western Man.
