His father was a Ukrainian Jew who had come to the U.S. at age 16, and his mother was an Irish-American Catholic. Eventually, the family moved to Cumberland, Wisconsin, and then to Green Bay, where his parents owned and operated the Bay Beauty Shop until after World War II, when they bought a home in Allouez and set up a beauty parlor there. Samuel worked in a paper mill in DePere and Josephine continued to run the hair salon. In 1935 Leonard's brother Jack was born, followed in 1940 by his sister Sandra.

In 1957, while they were graduate students at the University of Wisconsin, Leonard Swidler and Arlene Anderson were married. They have two daughters, Carmel (born 1958) and Eva (born 1962), and one granddaughter, Willow (born 2000). Leonard and Arlene Swidler lived in Philadelphia since 1966. Arlene died at home in 2008 after suffering from Alzheimer's for 17 years.^[3]
