Deiro family.

The Deiro collection comprises materials related to the professional and personal lives of Guido Deiro (1886-1950), Pietro Deiro Sr. (1888-1954) and Pietro "Lee" Deiro Jr. (1913-1999).

Immigrating from Italy to the United States in the early 1900's, the Deiro brothers Guido and Pietro, made enduring contributions to the popularization of the Piano Accordion in the 20th Century. As masters of the instrument, the Deiro's achieved headliner status on the vaudeville theatre circuit. Both composed, arranged and recorded an impressive repertoire of accordion music. Pietro Deiro Publications produced a catalogue of over 10,000 pieces of sheet music and instructional materials for the Piano Accordion. This collection documents not only a singular segment of American musical history but also a unique aspect of the Italian-American experience in 20th Century America.
