OBITUARIES By Bart Barnes Washington Post Staff Writer Friday, November 14, 2003; Page B05 Chester Petranek, 87, former supervisor of music for the Montgomery County schools who also was founder and director of the Montgomery County Youth Symphony and the Montgomery County Symphony, died Nov. 7 at Hillhaven Nursing Home in Adelphi after a stroke. For 47 years, Mr. Petranek was conductor of the Youth Symphony and the County Symphony, both of which he founded in 1946. He retired from the county schools in 1976 after 30 years of service. During that period, he taught music at 13 elementary schools and three junior high schools. He also taught band and orchestra at Bethesda-Chevy Chase High School. He was named supervisor of music in 1960. To his aspiring young musicians, Mr. Petranek was known as a tough and demanding disciplinarian who tolerated no foolery. "The kids have to learn that I'm the conductor and that the conductor's in charge. That's the way it is in the professional world. This is very serious in terms of their future," he told The Washington Post in 1982. He was known to boast that the 100 or so young musicians playing in his youth orchestra constituted the "best youth orchestra in the whole area . . . possibly in the whole United States." To win a seat in that orchestra, candidates had to pass a personal audition with Mr. Petranek. That generally included a prepared recital and an on-the-spot exercise in musical sight reading. Many failed to make the cut. Those who passed could expect at least two hours a week of rigorous rehearsal and practice of music by the likes of Brahms, Beethoven, Wagner, Dvorak, Tchaikovsky, Stravinsky, Mozart and Haydn. They would perform at such venues as the Concert Hall at the Kennedy Center and in auditoriums throughout the region. The best of them would go on to careers as professional musicians with such ensembles as the Philadelphia Orchestra, the Cleveland Symphony, the Metropolitan Opera and the Chicago Symphony. Mr. Petranek , a Silver Spring resident, was born in Cedar Rapids, Iowa, and graduated summa cum laude from Iowa's Coe College, where he majored in viola and violin. Later, he received a master's degree in supervision and administration from George Washington University. During World War II, he served in the Army, where one of his assignments was directing the band at the Walter Reed Army Medical Center in Washington. He remained in this area after the war, commenced his career with the Montgomery County public schools and organized the Montgomery County Symphony and the Youth Symphony, essentially to give the musically talented an opportunity to showcase their abilities. In the 1950s, he studied conducting under the famed Pierre Monteux, who led the San Francisco and Metropolitan Operas, the Boston Symphony and several European orchestras. For 21 years, until he stepped down in 1976, he played viola in the National Gallery Orchestra and also played in other orchestras and chamber ensembles in the area. In 1966, he founded a summer music camp at Deep Creek Lake in Western Maryland, supported by state and federal funding. The operation evolved into the Maryland Center for the Arts. Mr. Petranek was a former president of the Maryland Music Educators Association and a member of the American Federation of Musicians. His marriages to Mabel Wirth and Doris Gazda ended in divorce. His companion, Helen Turner, died in 2000. Survivors include three children from his first marriage, Stephen L. Petranek of Chappaqua, N.Y., Gary Petranek of Colesville and Kathleen Moody of Key West, Fla.; two children from his second marriage, Andrew Petranek of Los Angeles and Doriann Petranek of Tucson; eight grandchildren; and 17 great-grandchildren.
