Walter Harry Lisowski, 69, of Northeast Philadelphia, a retired transportation manager, died of Alzheimer's disease Tuesday, Dec. 13, at Chapel Manor in Philadelphia.

In 1965, Mr. Lisowski joined United Engineers & Constructors in Philadelphia. He worked as a blueprint interpreter while studying mechanical engineering at night at Temple University. Later, he was an expediter before becoming logistics and transportation manager for the company, which in 1969 became a subsidiary of Raytheon Inc.

Mr. Lisowski's projects for United Engineers included Three Mile Island and the Salem and Seabrook nuclear plants. Other projects took him abroad, including to China, Japan, Pakistan, and Saudi Arabia.

His last overseas assignment involved the construction of a methane power plant in a jungle in West Africa. The project was difficult, he told his wife, Ruth, because the vegetation would be cleared, and within days, it would grow back again.

He retired in 2000.

Mr. Lisowski grew up in Port Richmond and graduated from North Catholic High School. He served in the Air Force in England.

He and his wife met when he was working in a drugstore in Port Richmond where she was a customer. They married in 1963.

While helping to raise their family, he was active with Cub Scout Pack 266 in Northeast Philadelphia. For the pack's 25th anniversary in 1978, he and two other leaders organized a can- and paper-collection drive to fund a free chartered trip to Walt Disney World for the scouts.

Mr. Lisowski enjoyed woodworking and arts and crafts. He loved Christmas, his wife said, and made elaborate outdoor and indoor holiday dioramas, including one with a moving rocking horse under a decorated tree with a music box that played "White Christmas." He gave his work to friends and family and sold it at craft shows.

Mr. Lisowski played Santa Claus for family and friends and for events at Glen Foerd mansion in Torresdale.

In addition to his wife, he is survived by a son, David; a daughter, Audrey Nagel; two sisters; and two grandsons.

Friends may call from 7:45 to 8:45 a.m. Saturday, Dec. 17, at Fluehr & Sons Funeral Home, 3301 Cottman Ave. A Funeral Mass will be said at 9:30 a.m. at St. Matthew Roman Catholic Church, 3000 Cottman Ave.

Donations may be made to the Alzheimer's Association, 399 Market St., Suite 102, Philadelphia 19106.
