The Matthew Williams Stirling and Marion Stirling Pugh papers, 1876-2004 (bulk 1921-1975), document the professional and personal lives of Matthew Stirling, Smithsonian archaeologist and Chief of the Bureau of American Ethnology (1928-1957), and his wife and constant collaborator, Marion Stirling Pugh. The bulk of the material is professional in nature and includes material from Matthew's early career in the 1920s, the careers of Matthew and Marion together from when they married in 1933 to Matthew's death in 1975, and Marion's life and work from 1975 until her death in 2001. The majority of the documentation relates to the investigation of the Olmec culture in Mexico by the Stirlings, including the discoveries of eight colossal Olmec heads. In addition, the collection documents their work in Panama, Ecuador, and Costa Rica, looking for connections between Mesoamerica and South America. Materials include field notes, journals, correspondence, photographs, writings, clippings, ephemera, articles, and scrapbooks.

The Emmet Family papers document the lives and careers of two generations of the Emmet family from New Rochelle, New York and Stockbridge, Massachusetts, whose artistic talents flourished during the later 19th through the mid-20th centuries.

Through biographical material, two diaries, correspondence, writings and notes, exhibition files, business records, printed material, two scrapbooks, artwork, and photographs of family, friends, exhibitions, and artwork, the papers provide both a rich overview and detailed insights into the daily lives, relationships, and careers of many members of the family.

This collection contains two groups of photographs.

Benner.

The records of the Catherine Viviano Gallery measure 11.6 linear feet and date from 1930-1990, with the bulk of the materials dating from 1949-1978. Established in New York City in 1949, the gallery specialized in contemporary painting and sculpture primarily by American and European artists. The collection consists of artists' files; correspondence with artists, collectors, dealers, museum directors, curators, and publishers; business records; printed material; and photographs of artwork and artists. Also included are records relating to Catherine Viviano's activities as a private dealer and consultant after she closed the gallery in 1970.

Extensive professional and personal correspondence, 41 diaries, a large number of his published and unpublished writings, and subject files document Friedman's career as a writer, relationships with cultural institutions and art world figures, and his personal life.

Harrington was a Bureau of American Ethnology ethnologist involved in the study of over one hundred American tribes. His speciality was linguistics. Most of the material concerns California, southwestern, northwestern tribes and includes ethnological, archeological, historical notes; writings, correspondence, photographs, sound recordings, biological specimens, and other types of documents. Also of concern are general linguistics, sign language, writing systems, writing machines, and sound recordings machines. There is also some material on New World Spanish, Old World languages. In addition, there are many manuscripts of writings that Harrington sketched, partially completed, or even completed but never published. The latter group includes not only writings about anthropological subjects but also histories, ranging from a biography of Geronimo to material on the history of the typewriter. The collection incorporates material of Richard Lynch Garner, Matilda Coxe Stevenson, and others. In his field work, Harrington seems sometimes to have worked within fairly firm formats, this especially being true when he was "rehearing" material, that is in using an informant to verify and correct the work of other researchers. Often, however, the interviews with informants (and this seems to have been the case even with some "rehearings") seem to have been rather free form, for there is a considerable intertwining of subjects. Nevertheless, certain themes frequently appear in his work, including annotated vocabularies concerning flora and fauna and their use, topography, history and biography, kinship, cosmology (including tribal astronomy), religion and philosophy, names and observations concerning neighboring tribes, sex and age division, material culture, legends, and songs. The fullness of such materials seems to have been limited only by the time Harrington had to spend with a goup and the knowledge of his informants.

The records of New York City Kraushaar Galleries measure 106.3 linear feet and 0.181 GB and date from 1877 to 2006. Three-fourths of the collection documents the gallery's handling of contemporary American paintings, drawings, and sculpture through correspondence with artists, private collectors, museums, galleries, and other art institutions, interspersed with scattered exhibition catalogs and other materials. Also included are John F. Kraushaar's estate records; artists' files; financial ledgers documenting sales and gallery transactions; consignment and loan records; photographs of artwork; sketchbooks and drawings by James Penney, Louis Bouché, and others; and two scrapbooks.

Materials date from circa 1959-1999, with the bulk from 1990-1999.
