Although the John Landowski collection is small in size, it presents excellent visual and written documentation of his career, and of the history of the Milwaukee Polish Opera Club.
Personal papers in the John Landowski collection include a biographical sketch, a Xeroxed copy of the Landowskis' wedding announcement and photograph, news clippings concerning Landowski's activities and anniversaries as church organist, and personal and family photographs. With the photographs are several of Landowski; a photograph of Landowski and his children, the latter in costume for the production of Erminie (1946), and a 50th anniversary photo of Mr. and Mrs. Landowski. There is also a handwritten constitution, in Polish, of the St. Cecilia Choir at St. Vincent de Paul's Church (1906), and a folder of programs. Among the latter are programs from Halka, When the Moon Rises, and Erminie, and a 1958 jubilee program from St. Hyacinth's Church. The files of photographs, xeroxed copies of photographs, and news clippings of contemporary reviews together illustrate the productions of the Opera Club. Four of the Club's productions are represented, Martha, Il Trovatore, Halka, and Masked Ball, in additions to the two later operatic presentations of St. Hyacinth's Choir. There are numerous photos of actors and the casts in costume, most of whom are identified. Among the noteworthy actors are Anthony Lukaszewski, Rose Saskowski, Walter Schwabe, Eugene and Theresa Stachowiak, Anna Bartkowiak, Carl Pawinski, and Albert Rappaport.
