NEW YORK. Dr. Peter Diamandopoulos died on April 1, 2015, in New York City, surrounded by his loving children. He was 86 years old.

Born in Heraklion, Crete, in 1928, Diamandopoulos attended Athens College, and immigrated to the United State in 1948 to attend Harvard University where he earned his BA, MA and PhD.

A lifelong educator, Diamandopoulos taught at the University of Maryland and at Brandeis University, where he served as dean of faculty from 1965 to 1971, and was chairman of the Philosophy Department from 1972 to 1976. He also served as director of studies at the Adlai Stevenson Institute of International Affairs in Chicago from 1969 to 1974.

Diamandopoulos was named president of Sonoma State University in California in 1977, and president of Adelphi University in Long Island in 1985. Following his tenure at Adelphi, he continued to pursue his love of teaching, serving as special assistant to the president and professor of philosophy at Boston University. He retired in 2008 and continued to actively support the efforts of his alma mater, as a trustee of Athens College.

A proud son of Greece known for his love of books, music, fine cigars and cognac, Diamandopoulos consistently questioned conventional attitudes and challenged everyone around him to strive for excellence.

He is survived by his children Ted Diamandopoulos, Cybele Diamandopoulos, Ariadne Diamandopoulos; step-daughter Mary Blackstock; grandchildren Harry, Teague, Rita, Teddy; step-granddaughter Sofia Bocchino; and brother Dr. George Diamandopoulos.

A memorial service will be held at a date to be announced.
