In the 1970s, after retiring from the Army, he worked for Philco in Willow Grove and then was a project director for RCA in Camden until 1987.

For 16 years, Mr. Callaghan was a volunteer at Doylestown Hospital. He enjoyed woodworking and ceramics; daily swims; growing roses, African violets and vegetables; the beaches in North Carolina and New Jersey; and participating in a monthly neighborhood sing-a-long group.

Since 2004, he had been married to Deborah Rutherford Callaghan. In addition to his wife, Mr. Callaghan is survived by a daughter, Lisa Ettore; a son, Charles; stepchildren Jennifer and Michael Tesno; two brothers; and five grandchildren. Son James Jr. died in 1967.
