Benjamin J. Pensiero, 87, of Wyndmoor, a retired hospital administrator who taught business students at La Salle University for 34 years, died of heart failure last Saturday at Chestnut Hill Hospital.

Following his discharge, he earned a bachelor's degree from Franklin and Marshall, and later earned a master's degree in business administration from Temple University while working for RCA.

He was concerned about local government, his daughter Frances Carr said, and attended commissioners meetings and school board meetings in Springfield Township, Montgomery County. He was a frequent contributor to letters columns in local newspapers.

Mr. Pensiero enjoyed baseball, cooking, fishing, reading and crossword puzzles.

In addition to his daughter, he is survived by his wife of 60 years, Angelina Merlino Pensiero; another daughter, Janet; a sister; a brother; and two grandchildren.

A Funeral Mass will be at 11 a.m. Monday at Our Mother of Consolation Church, 9 E. Chestnut Hill Ave. Friends may call from 10 a.m. Mr. Pensiero was an usher at the church and was treasurer of its St. Vincent de Paul Society chapter.
