Frederick Fennell /fəˈnɛl/ (July 2, 1914 – December 7, 2004) was an internationally recognized conductor and one of the primary figures in promoting the Eastman Wind Ensemble as a performing group. He was also influential as a band pedagogue, and greatly affected the field of music education in the US and abroad. In Fennell's New York Times obituary, colleague Jerry F. Junkin was quoted as saying "He was arguably the most famous band conductor since John Philip Sousa."
