Jack died Christmas Day, 2002. A native of Montclair, N.J., he was the 10th of the 12 children of the famous industrial engineers, Frank and Lillian Gilbreth, about whom the books and movies Cheaper by the Dozen and Belles on Their Toes were written.
At Princeton, Gil was on the track team, managed the cross-country team, joined Dial Lodge, and majored in economics. He roomed with Bill Millar all four years.
He served in the Navy on minesweepers in the Pacific and was discharged as a radio technician in Dec. 1945. Joining McKinsey & Co. as a management consultant, Gil moved to Grace Line, and then retired after 22 years with Mobil Oil as industrial engineering manager of the international division.
Always active in his church, he was a member of the Society for the Advancement of Management, a Red Cross volunteer, and a member of the Nantucket Yacht Club and the Wharf Rat Club of Nantucket.
Predeceased by his wife of 47 years, Dorothy, Gil is survived by his sons, Peter and James; daughter Deborah Harrison; and three grandchildren.
