Samuel Hans Adler (born March 4, 1928) is an American composer and conductor.
Adler was born to a Jewish family in Mannheim, Germany, the son of Hugo Chaim Adler, a cantor and composer, and Selma Adler. The family fled to the United States in 1939, where Hugo became the cantor of Temple Emanuel in Worcester, Massachusetts. Sam followed his father into the music profession, earning degrees from Boston University and Harvard University (where he studied with Aaron Copland, Paul Hindemith, Paul Pisk, Walter Piston, and Randall Thompson and earned an M.A. in 1950). He studied conducting with Serge Koussevitzky at Tanglewood in 1949. Adler has been awarded honorary doctorates from Southern Methodist and Wake Forest Universities, St. Mary's College of Notre Dame and the St. Louis Conservatory of Music.
While serving in the United States Army (1950–1952), Adler founded and conducted the Seventh Army Symphony Orchestra. After his military service he was offered a conducting position just vacated by Leonard Bernstein on the faculty of Brandeis University but instead accepted a position as music director at Temple Emanu-El in Dallas, Texas, where the rabbi, Levi Olan, was a friend of Adler's family. Adler began his tenure in Dallas in 1953. At the Dallas temple he formed a children's choir and an adult choir and made the latter a prominent part of the religious services, often performing contemporary Jewish choral works that might otherwise have been neglected. From 1954 to 1958 Adler conducted the Dallas Lyric Theater. Adler is married to Dr. Emily Freeman-Brown of Bowling Green State University, who serves as Director of Orchestral Activities. From 1957 to 1966, Adler served as Professor of Composition at the University of North Texas College of Music. Between 1966 and 1995, Adler served as Professor of Composition at the Eastman School of Music Since 1997, Adler has been a member of the composition faculty at Juilliard and, for the 2009–10 year, was awarded the William Schuman Scholars Chair.
