Norman J. Fisher, 81, a physician in Hatboro for more than 30 years, died of heart failure March 20 in the Hatboro home he and his wife, Doris Meyers Fisher, commissioned celebrated architect Louis Kahn to design.

Kahn, whose building credits include the capital complex in Bangladesh, the Salk Institute in California, and the Kimbell Art Museum in Texas. Kahn worked on the Fisher house intermittently from 1960 until its completion in1967.

Over the years, Dr. Fisher told a reporter in 2004,  when architectural students would turn up at his door, "We show them through, especially if the house is clean." His home was his pride and joy, his daughter Nina Fisher DeKornfeld said.

A native of North Philadelphia, Dr. Fisher graduated from Central High School. He earned a bachelor's degree from St. Joseph's University and a medical degree from Thomas Jefferson University and completed an internship at the former Mount Sinai Hospital in Philadelphia. During the Korean War, he served in the Air Force in Japan.

After his discharge in 1953, Dr. Fisher married and established a general medical practice in Hatboro. He also served for a time as Hatboro's health commissioner. He retired in 1987.

Dr. Fisher was involved with a tree-planting program in Hatboro and was active in efforts to improve Pennypack Creek. He enjoyed vacations in Northern Vermont, music and woodworking. He made furniture and picture frames, his daughter said, and toys for his grandchildren.

In addition to his wife and daughter, he is survived by another daughter, Claudia Gohl; a brother; and five grandchildren.

Services were private.
