LEWES, Del. (AP) – Internationally acclaimed conductor Frederik Prausnitz, who promoted contemporary classical music, has died.

Prausnitz died Nov. 12 of cancer at his home in Lewes, according to his daughter. He was 84.

Prausnitz worked with several American and European orchestras and served on the faculties of New York’s Juilliard School, Boston’s New England Conservatory and the Peabody Institute’s conservatory in Baltimore.

His recordings included works by Carl Ruggles (“Lilacs” and “Portals”); William Walton (“FaEcade,” with Dame Edith Sitwell reading her poetry); Elliott Carter (Double Concerto and Variations for Orchestra); and Roger Sessions (Rhapsody for Orchestra, Eighth Symphony and “Montezuma”).

His books included “Roger Sessions: How a Difficult’ Composer Got That Way,” published in 2002, and “Score and Podium: A Complete Guide to Conducting,” published in 1983.

His marriages to Evelyn Prausnitz and Marion Prausnitz ended in divorce. Margaret Britten Prausnitz, whom he married in 1961, died in 1999.

Survivors include two children from his third marriage, F. Sebastian Prausnitz of Baltimore and M. Maja Prausnitz of London, and a brother, Walther Prausnitz of Moorhead, Minn.

A memorial service will be held Dec. 4 at 1 p.m. at St. George’s Chapel in Dagsboro.
