His wife, Nancy, said both events are open to the public.

Mr. Stokking, who retired from the orchestra in 2005, died Sunday, Dec. 14, 2014, at a Moorestown nursing home of complications from a stroke.

He joined the Philadelphia Orchestra in 1960, then played with the former Chamber Symphony of Philadelphia, the Boston Philharmonic, and the Cleveland Orchestra, before returning to the Philadelphia Orchestra in 1973.

A native of Ventnor and a lifelong New Jersey resident, Mr. Stokking studied at Curtis and the Juilliard School.
