On Monday, Sept. 30, Mr. Szczepkowski, 89, a cofounder of his family's electronics firm in Moorestown, died at Trident Hospital in Charleston, S.C., after an accident.
He had lived in Sarasota, Fla., since retiring in 1990 as president of SWEMCO, which offers electronic manufacturing services and electronic engineering design.
In 1965, he had joined his brother, Ted, brother-in-law Ed Wolaniuk, and friend Ed Smith in founding the firm, his son said.
Born in the Polish city of Torun, birthplace of the astronomer Copernicus, Alfred Szczepkowski emigrated with his family to the United States in 1933, when he was 9.
He graduated from West Philadelphia High School in 1942, enlisted in 1943, and took classes at the University of Alabama while in boot camp nearby.
By the time he was discharged in 1945, his son said, he was a captain who had declined a promotion in order to return to his college studies.
He had been wounded three times, twice by rifle fire and once by mortar shrapnel, his son said.
In the house-to-house combat common for frontline troops, his son said, Mr. Szczepkowski and his buddies had once been captured. But the Germans had retreated, leaving the Americans behind and alive.
"He talked about unfortunately having killed more than he knew," his son said. "A lot of hand-to-hand combat. Not only a matter of the enemy dying, but a lot of his own brothers died."
After the war, Mr. Szczepkowski earned bachelor's degrees in electrical engineering and mechanical engineering and a master's in business administration, all at Drexel University.
While taking classes at the University of Pennsylvania in the early 1950s, he happened to walk through the facility where one of the first computers was being built.
"Watching technicians stringing cables" endlessly, his son said, "he commented, 'This will never work.' "
He met his future first wife, Leonore Wolaniuk, at a Polish American club in Philadelphia. Their marriage lasted from 1951 until her death in 1998.
A classical violinist, she was a freelancer for Broadway musicals playing in Philadelphia, as well as for homegrown musical groups.
"She actually started a South Jersey chamber orchestra at our home in Moorestown," her son said.
In addition to his son Carl, Mr. Szczepkowski is survived by his wife, Anya; sons Robert and Richard; seven grandchildren; and a great-grandson.
Graveside services are planned for Sarasota National Cemetery in Florida.
