Pierre Lucien Schoenheimer, a financier and decades-long summer resident of East Hampton, died at his apartment in Manhattan on Jan. 25. The family did not provide a cause of death. He was 79.
Mr. Schoenheimer’s parents purchased a house in Montauk in the 1950s. He and his family remained connected to the area ever since.
Mr. Schoenheimer was born in Paris in July 1933 to Fritz R. Schoenheimer and the former Ellen Berliner. The family fled Europe in 1941, ultimately settling in New York.
A graduate of the Horace Mann School in Riverdale, N.Y., he received a bachelor’s degree from New England College and a master’s degree from Columbia University. Mr. Schoenheimer also participated in the Owner/President Management Program, an executive program run by Harvard Business School.
He had three children with his first wife, Janet Gersten, who survives. His second wife, Idee German, survives as well.
Described by his family as an “entrepreneur, philanthropist, and tour de force,” Mr. Schoenheimer had success in the worlds of business and philanthropy, serving on many boards. In 1970, he founded the Radix Organization, a private investment banking firm. He also co-founded the Austin Capital and Radix Sterling Fund, a fund of hedge funds.
Whether in business or philanthropy, Mr. Schoenheimer devoted great energy and passion to the fields of education, science, and research. He also served on the board of the Weizmann Institute of Science, and was a board member for many years at the Jewish Center of the Hamptons.
In addition to his wife, he is survived by his children, Joyce Oleshansky of Honolulu, Linda McCurdy of New York, and Daniel Schoenheimer of Montauk. He also leaves seven grandchildren and four great-grandchildren.
A memorial service is to be held this summer at the Jewish Center.
