Like so many others of that great generation, Jack got on with his life after the war, helping to build a stronger nation by living the American dream. Great success in the insurance business allowed him to turn his good fortune toward philanthropic endeavors, and he often donated significant sums of money and much of his valuable time to worthwhile causes.
The Navy is among the many beneficiaries of Jack's generosity. He donated both time and money to a number of Navy organizations, making things happen that otherwise might not have been feasible. Among many other contributions, he provided vital support for the commissioning of the attack submarine USS Cincinnati (SSN-693), he served on the National Board of Directors of the Navy League and as a trustee of the USS Constitution Museum, and his support and counsel to the U.S. Naval Institute earned him an appointment as Honorary Commodore in 1991.
Although nothing more was expected of him, Jack Schiff demonstrated a kind of quiet heroism by continuing to give back to the nation and to the Navy in a multitude of ways long after hanging up his uniform for the last time. His selfless service and his generosity earned him the respect of all who knew him and caused the Secretary of the Navy to award him the Navy's Superior Public Service Award in 1997. Although he consistently avoided personal recognition for his philanthropic work, today there is a Jack Schiff Memorial Library at the St. Mary's Submarine Museum in Georgia, and the U.S. Naval Institute's board room prominently bears his name.
