Nicholas Slonimsky (April 27, 1894 to December 25, 1995) was a Russian composer, conductor and scholar. He wrote studies entitled things like Sex and the Music Librarian. Among his many books is a Thesaurus of Scales and Melodic Patterns (1947). Slonimsky was the first conductor of many avant garde pieces, such as some by Charles Ives. He had the grace and humility of real genius. Frank Zappa was a friend and Slonimsky not only performed his own work occasionally at Zappa concerts, Nicholas Slonimsky named his cat Grody-to-the-Max after he learned this phrase from Zappa's daughter.
