According to his wife Vera, in 1951 Leckie was inspired to write a memoir after seeing South Pacific on Broadway and walking out halfway through it. He said, "I have to tell the story of how it really was. I have to let people know the war wasn't a musical."
He married Vera Keller, a childhood neighbor, and they had three children: David Leckie, Geoff and Joan.
Leckie died on December 24, 2001, six days after his 81st birthday, after fighting a long battle with Alzheimer's disease. He was survived by his wife of 55 years, his three children, two sisters, and six grandchildren. His remains were entombed at St. Joseph's Mausoleum in Newton, New Jersey.
