The Guido Deiro Section of the Deiro Archive was donated to The Center for the Study of Free-Reed Instruments, The Graduate Center, The City University of New York, by Count Guido Roberto Deiro of Las Vegas in March 2001. The Archive consists of memorabilia of the careers of his father, Guido Deiro, and his uncle, Pietro Deiro, pioneering piano-accordionists in America. Part of the collection was passed to Count Deiro by his father (who died in 1950); the remainder was assembled by Count Deiro over a period of many years. The collection is divided into two parts, recordings and printed items. The Archive’s materials are subdivided as follows: Part I: Recordings Ten-Inch 78s Twelve-Inch 78s Cylinders Audio Cassettes Index of titles of recordings Part II: Printed Items Books General Memorabilia Scrapbooks
