The Michael Cummings Collection of P.S. Gilmore Materials documents the life and music career of Irish-American Patrick Sarsfield Gilmore and highlights the activities of the Patrick S. Gilmore Society, founded by Michael Cummings in Boston in 1969. The collection was artificially created by Michael Cummings and includes correspondence, concert programs, photographs, and lithographs, audio and visual recordings, and newspaper and magazine articles. Much of the material documents the National Peace Jubilee of 1869 and the World's Peace Jubilee of 1872, both held in Boston, Massachusetts. In addition, the correspondence and newspaper articles from the nineteenth century are copies of original documents.
