Lennie Niehaus (1929–2020) was an American saxophonist, composer, arranger, and educator whose name is inextricably linked with the history of 20th-century jazz and film music. He studied at California State University in Los Angeles, where he received formal musical education, and shortly thereafter became a saxophonist in Stan Kenton's jazz orchestra. It was here that he made a name for himself not only as an excellent player, but also as a respected arranger who brought new elements to the big band sound. In addition to his jazz activities, Niehaus also made a name for himself as a film music composer, writing the music for The Untouchables (1992) and Midnight in the Garden of Good and Evil (1997), among others. In the field of education, he created a number of method books for wind instruments, including the popular series Jazz Conception and Jazz Inventions, which help players master the stylistic elements of jazz.
