Jack Daly was a Kennedy neighbor in Hyannis Port. Daly was Chairman of the board of Republic Aviation and sent insider stock trading tips to Jack when he was a Harvard student.
He supplied a reference for young Jack as he was joining the US naval reserve.
(Jack)…. is the most intelligent boy in the Kennedy family, has a very active mind, reacts quickly and is a damn good sailor. I have had occasion to race against him frequently and he handles his sails like an old veteran. He is an exceptional lad and I can not recommend him too highly.
