Frank W. Lewis has constructed cryptic crosswords as a hobby for The Nation since 1947. Although trained as a musician (with a Master of Music degree) possessing some talent as a conductor, particularly for choral groups, Mr. Lewis worked for thirty years as a cryptanalyst for the War Department and the National Security Agency. Much of his work is still classified. He and his wife retired to the Caribbean in 1969 but had to relocate to Massachusetts after the Montserrat volcano blew. They have five children.
