In 1931, as a gift on his first visit to Europe, Al Fenn (1912-1995) was given a Leica. By the time he returned to the States, his “heart now belonged to photography.” During Fenn’s 15 years at LIFE, his subjects were diverse, from baby birds to boxers. Fenn’s father was a physics professor and his mother an actress. “It seems quite logical.” he concluded, “that I should be a photographer, which is apparently the genetic result of the mixture of science and art.”
