Walter C. Allen family donates research library The Allen family of Brick has donated their father, Walter C. Allen's, complete library of materials to the Fletcher Henderson Museum. Walter C. Allen was a jazz historian at the Smithsonian Institute, Washington, D.C., and was considered an expert on the career of Fletcher Henderson. He was also one of the founding members of the Institute of Jazz Studies at Rutgers University. Allen's monograph, "Hendersonia: The Music of Fletcher Henderson and His Musicians," is now considered the authoritative work on Henderson's career, according to a press release sent to the Brick Bulletin. The Allen collection includes vintage sheet music, early recordings, autographed first-edition books, recorded interviews, musical arrangements, rare photos, piano rolls, vintage magazines, portraits and many other items.
