Papers, 1840-1956, of Joseph Keppler, cartoonist and founder of the magazine "Puck," and of his son, Udo J. Keppler, later known as Joseph Keppler, Jr. They consist of correspondence in English and German, dealing with "Puck," cartoons, personal and family matters, and a wide range of other papers and printed ephemera. There are legal and financial papers, some dealing with the affairs of "Puck," including share certificates, accounts, bills of exchange, and a printed announcement of the first issue of "Puck". Personal papers of Joseph Keppler include a school report, certificates of attendance at various art schools in Vienna, his contract when he was employed as an actor in Vienna in 1864, his smallpox vaccination certificate, and his Austrian and U.S. passports. There are also prompt books and a commonplace book in German, and some printed books (plays, and cartoons by Wilhelm Busch), as well as a broadsheet in German announcing a puppet show, probably late eighteenth or early nineteenth century. Udo Keppler's papers include correspondence, school reports, his passport, a sketch by him, and a commonplace book. The correspondence deals with reminiscences of "Puck" and cartooning, personal and family matters, and Udo Keppler's interest in Native American affairs (he was adopted by the Seneca under the name Gyantwaka). It includes letters and cards from Theodore Roosevelt, Joseph Pulitzer, Charles A. Dana, William Jennings Bryan, Grant E. Hamilton, Samuel W. Lambert, Hermann Urban, Art Young, and Joe Scheuerle; the Young and Scheuerle material includes some original sketches, and there are several of Art Young's Christmas cards. There are numerous clippings, obituaries, and miscellaneous pieces of printed matter. Some letters sent to Udo Keppler's widow Vera are mostly related to her donations of his papers and property to various museums, but it includes a number of letters from Draper Hill about his thesis on Joseph Keppler. There are also copies of the last German edition of "Puck," and Pucks Volkskalendar für 1879; some photographs, including a tintype of Udo Keppler as a baby; and numerous condolence cards and letters on Udo's death. An autograph album belonging to E. Jennie Miller dates from the 1880s.
