William J. Cassidy, 93, of Philadelphia, a former chief of orthopedic surgery at Northeastern Hospital, died Thursday, Feb. 20, of dementia at St. Joseph's Manor in Meadowbrook.

A Philadelphia native, Dr. Cassidy graduated from St. Joseph's Preparatory School in 1938 and from St. Joseph's College with a bachelor's degree in 1942.

He completed his medical degree at Temple University Medical School in 1945. He was a physician in the Navy Medical Corps during World War II.

On release from active duty, Dr. Cassidy set up a family practice in the Mount Airy section of Philadelphia.

But in mid-career, he found himself drawn to the specialty of orthopedic surgery, returning to Temple for a residency in the specialty. He earned a master's degree in orthopedic surgery from Temple and did advanced study at the University of Pennsylvania's Graduate School of Medicine.

Dr. Cassidy practiced orthopedic surgery at St. Mary's Hospital in Fishtown and St. Mary Medical Center in Middletown, Bucks County. He was chief of orthopedic surgery at Northeastern Hospital in Kensington until his retirement in 1986.

His daughter, Susan M. Cassidy, said her father was cheerful, friendly, and down-to-earth in both his practice and his personal life.

"Everyone loved him," she said. "He was very kind. He came from nothing and built a wonderful life for us. He worked from the time he was very young."

Dr. Cassidy was a member of the American College of Orthopedic Surgeons.

In retirement, he enjoyed fishing and sailing at his summer home in Ocean City, N.J., and his winter home on Captiva Island, Fla.

Dr. Cassidy was married to the former Dolores "Bonnie" Connor, also of Philadelphia. She died in 2009.

In addition to his daughter, he is survived by sons William J. Jr. and Michael P., and four grandchildren.

A 10 a.m. viewing Tuesday, Feb. 25, will be followed by an 11 a.m. Funeral Mass at St. Albert the Great Roman Catholic Church, 212 Welsh Rd., Huntingdon Valley. Interment will be in Holy Sepulchre Cemetery.

Donations may be made to St. Joseph's Preparatory School, 1733 W. Girard Ave., Philadelphia 19130.
