Pickle died June 13, 2007, at his retirement home, Stonebridge, just outside Princeton.
He was a graduate of the Hotchkiss School and majored in geology at Princeton. A member of the freshman hockey and tennis teams, he played on the championship 1941 hockey team, and was awarded the Blackwell Cup as the player who, in sportsmanship and influence, most contributed to the sport.
In 1942, Pickle was commissioned an ensign in Naval intelligence. During his four years in the service, he spent 30 months in the central Pacific and the interior of China. After separating from the Navy, he joined Rome Cable Co., leaving in 1966 to take his family to Grenoble, France, where he began studying for his next career as French instructor at Princeton Day School, where he was also hockey and tennis coach. He retired in 1979.
He was a member of the Nassau Club, Bedens Brook Club, Pretty Brook Club, and the Nassau Gun Club. He served on the boards of the Experiment in International Living and the Langeloth Foundation.
Pickle is survived by his wife of 60 years, Ann Rooney Hochschild Poole; his daughter, Kathrin; his sons, Richard, Peter, and Walter; and eight grandchildren.
