Peter Kollisch was born in Baden, Austria in 1928, the son of the architect Otto Kollisch and the poet Margarete Kollisch.
In 1923 Margarete Moller married the architect Otto Kollisch. They had three children: Stefan (later Steve), Peter, and Eva. In 1939 the family began to leave Austria: the children left first on a Kindertransport to England in July 1939, while Otto Kollisch immigrated to the United States via England in August 1939, and Margarete Kollisch travelled via Holland, arriving in the U.S. in October 1939. The children followed their parents to America in April 1940, when the family was reunited and settled in Staten Island.
