James M. Rock, 84, advertising sales representative

James M. Rock, 84, of Bryn Mawr, a former advertising sales representative, died Sunday, Sept. 30, at Bryn Mawr Hospital.

Mr. Rock was born in Marshall, Minn., graduated from the University of Minnesota, and was in the armed services.

He met his wife, Rita Ann, who died in 1999, while they were working one summer at Glacier National Park, according to their daughter, Anne Rock Maurer. "They were the best of friends, complemented each other perfectly," she said.

Mr. Rock spent most of his advertising sales career at the Farm Journal, the nation's oldest agricultural publication, in Philadelphia.

"He was very collegial and friendly not just with his own clients, but even with the competition," his daughter said, adding that clients quickly became friends.

Mr. Rock and his wife lived on the Main Line for 50 years and traveled extensively. They belonged for many years to the Waynesborough Country Club in Paoli and the Down Town Club in Philadelphia.

The funeral was private.

Memorial gifts may be made to the Rita Ann Barry Rock Scholarship at Dominican University, University Advancement, 7900 W. Division St., River Forest, Ill. 60305.
