Jack died Jan. 25, 2020, at his home in Greenwich, Conn.
A Blair Academy graduate, he volunteered for the Army in 1943 and served as a staff sergeant in a frontline mortar squad in France and in Germany. He belonged to Tiger, majored in the School of Public and International Affairs, and graduated with high honors.
Jack originally started with Ford Motor Co. but soon left for a job on Wall Street, where he worked in securities sales for Goldman Sachs for 35 years. He relished commuting from his Tenafly, N.J., home to Wall Street on his motorcycle.
Jack’s sense of adventure abounded throughout his life. He took motorcycle trips from New Jersey to California, and from Italy to Denmark. He took up scuba diving and sea kayaking. He delighted his children by his impromptu visits to them, sometimes in his Morgan sports car, top-down, or in his Husky airplane, which he would land in the nearest grass airfield. (He flew into his 70s.) His adventuring was complemented by his encyclopedic knowledge of history and love of poetry.
Jack married Rosemarie Lanigan in 1950 during his senior year. She predeceased him in 2010. They are survived by their five children, 14 grandchildren, and six great-grandchildren.
