Theoretical physicist Edward Uhler Condon documents three decades of his professional career through 35 volumes of appointment books and planners (1939-1971). Although his entries are necessarily sparse, these notebooks ought to interest scholars researching his professional activities in government, industry, and the academy (most especially his tenure at Princeton University). Condon recounts a range of professional engagements, including his teaching schedule, meetings, conferences, proposals, and book manuscript development. Notably, early entries register some religious practices (Jewish), such as meetings with rabbis (e.g. 4/16/1939, 10/19/1939), and mounting concerns related to World War II (beginning 3/16/1939). Later journals document his rising professional star, including a memo inviting him to participate in a meeting at Library of Congress (11/7/1949) and National Science Foundation (11/9/1957). Researchers interested in his career will find detailed records of his professional networks, including the names, contact details, and occasionally business cards of associates.
