Irving McClure Johnson (July 4, 1905 – January 2, 1991) was an American sail training pioneer, adventurer, lecturer and author.
Johnson was born in Hadley, Massachusetts, the fifth child of the author Clifton Johnson and Anna Tweed McQueston.
Early home movies show him training for a life at sea, climbing a telephone pole in his backyard, and wrestling & Jiu Jitsu to prepare for the inevitable fights he believed would occur due to his reading the novels of Jack London and Joseph Conrad.
