This index calendars correspondence to and from prominent figures represented in the Polanyi Papers between 1913 and 1975. An effort has been made to demonnstrate the wide range of Michael Polanyi's contacts. All scientists listed are those represented in the World Who's Who in Science (Chicago, 1968). As the correspondence is arranged chronologically with undated letters arranged alphabetically at the end of the series, indexed names are followed by the dates of their correspodance or, if there are undated letters, by the number of pieces followed by n.d. Correspodence with John R. Baker, Joseph H. Oldham, Marjorie Grene, Harry Prosch, Karl and Ilona Polanyi, and Cecile Polanyi follows the undated group.
