This series consists primarily of contact sheets, approximately 3600 black-and-white negatives, and photographic prints in various sizes, portraying notable Princeton professors, visiting scholars, politicians, scientists, artists, and musicians, mostly during the late 1950s through the early 1970s, though some were taken later. While some photographs pertain to assignments for the Princeton Packet, where Steltzer worked, many were shot independently in her studio on Tulane Street, often for passport photos. Steltzer's subjects include such diverse characters as J. Robert Oppenheimer and his family, Adlai Stevenson, Igor Stravinsky, George McGovern, Bob Dylan, Roger Sessions, Richard Rorty, Arthur Schlesinger, Jr., Benny Goodman, Paul Dirac, and David Lilienthal. Correspondence pertaining to later usage of prints, Xerox copies of prints and contact sheets, and CD-ROMs are also occasionally included with photographic materials. Though 8x10" prints are frequently interleaved with matching contact sheets and negatives, a group of oversize mounted prints, 16x20" and smaller, is also present in this series.

Dates were attributed to undated photographs, when possible, by locating the matching contact sheet or print of a different size. When a specific date could not be pinpointed, a date range was provided based on context.
