Long-time Radnor Hunt (Pa.) senior master and president of the Bryn Mawr Hound Show, Frank Hastings “Terry” Griffin III, of Devon, Pa., died of heart failure on Dec. 31. He was 62.

Born in 1946, Mr. Griffin graduated from Washington & Lee University (Va.) in 1968. After graduation, he was commissioned in the Marine Corps during Vietnam and served as an artillery officer. After leaving the military with the rank of Captain, he returned to school and graduated from Villanova University School of Law (Pa.) in 1974, where he was editor-in-chief of the Villanova Law Review.

As a practicing lawyer in Pennsylvania, Mr. Griffin successfully argued a landmark patent law case before the U.S. Supreme Court in 1996, winning a unanimous decision.

For nearly the past two decades, Mr. Griffin dedicated his efforts to reviving a flagging fox hunting program, which today has regained its centerpiece at Radnor. He was successful in gaining new hunting country and devoted countless hours, in recent years, explaining to community groups, legislators and anti-puppy mill advocates the distinction between well-run hunting kennels and puppy breeding operations.

Mr. Griffin continued to lead Radnor, regularly following in his Jeep, and was mounted at the meet marking Radnor’s 125th Anniversary on Dec. 16, 2008.

Mr. Griffin is survived by his wife of 40 years, Jeffory Horning Griffin, sons, Frank Hastings Griffin IV and James H. Griffin, his father F. Hastings Griffin Jr., one brother and two sisters.
