Jane Campbell Bannerman studied graphic design and illustration at the New York School of Fine and Applied Art (now Parsons School of Design), graduating in 1930. She worked for several firms as a graphic and interior designer, and later opened her own interior design business. The collection mainly consists of student work, commercial design work, and travel watercolors, as well as clippings, photographs, and printed items.

Lyman Martin (1908-2003) graduated from Parsons School of Design in 1939 and joined Thedlow, an interior decoration firm. At Thedlow, Martin created interiors and watercolor renderings, and designed rugs and murals. In 1969, Martin became president of Thedlow, remaining until its closure in 1979. The collection includes student work, interior drawings, a travel diary, floorplans, photographs, clippings, and exhibition files.

This collection is primarily concerned with Prof. James Renwick and his professional correspondence and papers, both as Professor of Natural Philosophy (Physics) at Columbia College and as a leading engineer. Many certificates of membership in honorary societies are included. There are letters from Washington Irving (1783-1859) to Prof. Renwick and to his mother, Jane Jeffrey Renwick, pertaining to contemporary events and Irving's own activities. The letters to Mrs. Renwick are about the travels and experiences of Irving and Renwick abroad. The collection also covers the affairs of the Prof. Renwick's grandfather, including documents concerning his land grants in New York State, and those of James Armstrong Renwick, including his valedictory address at Columbia College in 1876 and his class reunion in 1916. There are many legal documents, letters, and manuscripts of various members of the Renwick and Brevoort families; among these are Prof. Renwick's notes on his family genealogy and a memoir of Jane Jeffrey Renwick. Correspondents include Clement Clarke Moore, John A. Dix, Martin Van Buren, Secretary of State John Forsyth, and Secretary of the Navy James K. Paulding. There is one letter from Sir Edward Sabine (1788-1883), President of the Royal Society, giving his views on the American Civil War.

The collection consists of five photograph albums and three scrapbooks compiled by the designer, style arbiter, and Parsons School of Design administrator and president Van Day Truex (1904-1979).
