Born and raised in Philadelphia, Mr. Weaver graduated from Central High School, and from Cornell University in 1959 with a degree in chemical engineering.

He spent most of his career with Rohm & Haas Co., starting in research in 1969 and retiring in 1990 as vice president for environmental, health and safety, and engineering.

After that, he worked for eight years in the New York office of the American Institute of Chemical Engineers. Interested in social justice, he joined Esperanza Inc. and became dean of Esperanza College of Eastern University.

He served on the boards of nonprofits including Metropolitan Career Center, Taller Puertorriqueno, and Lutheran Settlement House. A longtime member of Advent Lutheran Church in Richboro, Bucks County, he served in many capacities.

Mr. Weaver loved music and travel. He took his family to Europe, Central America, all over the United States, and Canada.

"Our girls just loved to travel, and he took it into their adult years," said his wife, the former Linda Hollinger.

He sang bass in the Voices Chorale and toured Germany with the chorus. He spoke German, having spent a year at the University of Muenster on a Fulbright travel grant before obtaining his doctorate at the University of Delaware in 1965. He also sang in the chamber chorus Cantus Novus, of which he was president.

Mr. Weaver enjoyed touring Longwood Gardens, Chanticleer, and Morris Arboretum. He was a vegetable gardener, and loved the birds and other animals in the wild. He also supported many environmental causes.

He was a volunteer science presenter at the Franklin Institute and a docent at the Philadelphia Zoo.

Besides his wife of 48 years, he is survived by a daughter, Sonya; a brother; and nieces and nephews. A daughter, Sara, died earlier.
