The file contains the diary of Wilder Penfield for December 24 1970 to May 17 1972. The diary documents Penfield’s thoughts on current and past events and includes topics such as Helen’s health; the Vanier of the Family; commemorative stamps for Sir William Osler and Stephen Leacock; death of colleagues, Don McEachern and Dr. William Cone; travel accounts to House and Elba; officially moving from the house to the apartment; progress on No Man Alone, including deciding on the title and narrative style; Ted Rasmussen’s retirement; and family events, like Christmas. In addition, the diary contains the beginning of a journal entry by Helen, additional entries pasted into the pages, the account of weeding their personal papers, comment on the Lev Landau case, and letters, and potentially the plan to make a quilt out of his academic hoods. Penfield has gone through and corrected his grammar and spelling or has expanded upon his initial thoughts, usually in pencil or pen.
