Nicolas Slonimsky (April 27 [O.S. April 15] 1894 – December 25, 1995), born Nikolai Leonidovich Slonimskiy was a Russian-American musicologist, conductor, pianist, lexicographer, and composer.
Throughout his life, Slonimsky wrote extensively for periodicals and newspapers, produced program and liner notes, and contributed to numerous reference works. He is best known for editing Theodore Baker's Biographical Dictionary of Musicians.
This has to be my favourite dictionary. Its witty, lively and sometimes a bit subversive. Its a book to take to bed and to wonder at the amazing lives and phenomena of the most elusive of the arts.
