“He served as principal oboe of the Cleveland Orchestra from 1965 until his reluctant retirement, due to an eye condition, in 2001. During those 36 years, a record in the post, he played under three music directors — George Szell, Lorin Maazel and Christoph von Dohnanyi — and the conductor who would become music director in 2002, Franz Welser-MÖst. Along with his legacy of performances and recordings, Mack taught oboists who hold positions in orchestras throughout the United States and abroad.”
