Among his creations were French Creek Golf Club in Elverson; the Downingtown Country Club; Brandywine Square, and Whiteland Business Park in Exton.
Born in Philadelphia, Mr. Loew moved to Aiken, S.C., and from there to Wilmington, where he graduated from Mount Pleasant High School. He moved to West Chester in 1992, when he married his wife, a widow with four children.
After completing a course of study in architecture at what is now Carnegie Mellon University, he graduated from Washington University in St. Louis with a bachelor's degree in business administration.
Mr. Loew loved to travel the world with his family. Among his favorite adventures were African safaris and hot-air ballooning. Ten months ago, he climbed mountains in Asia to see the Tibetan monasteries, and trekked through the muck in the Rwandan jungles for a glimpse of wild silverback gorillas.
Mr. Loew had always wanted to "go eye to eye with them," and he was able to do that, seeing a male from a distance of six to eight feet, his wife said.
"The silverback stared right back at you, and was munching and munching," said his wife. "We were both in such awe."
One of Mr. Loew's other passions was philanthropy. After witnessing devastation in Sri Lanka on a tour one year after a 2004 tsunami, Mr. Loew contributed funding to build homes for families who had lost everything.
He supported Exceptional Care for Children, in Newark, Del., a facility that provides palliative care for terminally ill children. "He got them their building," his wife said.
Mr. Loew also supported Friends Association for the Care and Protection of Children, in West Chester, and Safe Harbor in West Chester, an organization that provides food and shelter to the homeless.
In addition to his wife of 22 years, he is survived by a son, Adam R.; a daughter, Amanda Loew Rocco; stepdaughters Noelle Burton Lachenmayer and Liane Burton Duncheskie; stepsons Robert C. Burton and Donald W. Burton; 19 grandchildren; his mother, Marian Lowe Kimmel; a sister; and his former wife, Mary Potts Cicone.
A memorial service will be held at 3 p.m. Friday, Feb. 7, at Downingtown Country Club, 85 Country Club Rd. Mr. Loew donated his body to science.
