The papers of "Jackrabbit" Johannsen reflect his personal, professional and recreational activities, mainly between 1934 and 1985. The largest part of the papers consists of correspondence with friends and organizations, particularly relating to skiing and outdoor life. Family relations are also covered. A series of brief journals provides a record of some of his daily activities, from 1948 to 1984. The remainder of the fonds include publications about Johannsen, photographs, maps and personal documents such as passports.

The fonds contains original and typescript letters, manuscript notes, newspaper clippings, journal extracts, reminiscences and more, assembled by Harvey Cushing chiefly between 1920 and 1924 during the course of his research for the biography of William Osler. For the biography, Cushing collected and retyped over 7500 pieces of Osler's correspondence, among which are some original letters.

The fonds is separated into three series: Manuscripts, Working Notes and Osler's Correspondence. It also contains photographs, annual reports, publications, clippings, one watercolor painting, one postcard. Osler's correspondence is further arranged in three subseries based chronologically.

The fonds contains chiefly of family correspondence between members of the Penfield and Chester families, as well as clippings and correspondence regarding Wilder Penfield's autobiography "No Man Alone" and correspondence regarding posthumous honours for Wilder Penfield. Family correspondence includes a 1917 letter from Helen Kermott (later Helen Kermott Penfield) accepting Wilder Penfield's marriage proposal. Much of the family correspondence is between Wilder and Helen Penfield and their daughter Priscilla and her husband William M. (Bill) Chester Jr., as well as Bill Chester's parents William (Sr.) and Alice Chester. There are incoming letters and many carbon copies of outgoing letters. A series of 1949 letters congratulates the young couple (Bill Chester and Priscilla Penfield) on their engagement. One letter is also between Wilder Penfield and George Chester. A few materials are related to posthumous honours for Wilder Penfield, such as the naming of a building after him at John Abbott College (letter to Wilder Penfield Jr.) and a 1982 speech given by Priscilla at the Penfield Children's Center (typescript copy). There is also correspondence between Bill Chester and William Feindel. One 1976 carbon copy of a letter (1976) details the period following the death of Priscilla's father, Wilder Penfield, while the couple was in Japan. Materials related to "No Man Alone" include clippings from journals and newspapers of reviews and book announcements, as well as two copies of the book jacket and some related correspondence.

Fonds consists of Dr. Ewen Cameron's teaching materials, articles, addresses, and a file of material regarding the Nazi leader Rudolf Hess and his claims of amnesia during the Nuremberg trials in 1946, as well as a couple files of biographical interest on Cameron. Teaching materials consist of notes for a seminar on tension and anxiety for military psychiatric personnel (1943). Articles and addresses comprise a draft, with letter from the McGill Medical Journal, an article on psychiatric education (1944) an address to the American Psychiatric Association on day-hospitals (1947), opening remarks for the World Congress of Psychiatry meeting (1961), and "Some thoughts on my years as director of the (Allan Memorial) Institute" (1964). There are also a few reprints of articles on memory, psychiatric training, and hospitalization.

Biographical materials consists of a copy of Cameron's letter of appointment at McGill (1943), and a biographical sketch by Dorothy Trainor of the Allan Memorial Institute.

Fonds consists of correspondence and literary manuscripts, documenting all aspects of MacMillan’s career. Biographical background is provided by his own notes on his life and family history. From his student years come certificates and testimonials in support of his application for a Rhodes Scholarship (1904-1909). His war experience is recorded in letters from the front preserved by his family, and by a personal diary for 1917. There are also approximately twenty photographs of Macmillan and his family taken between about 1905 and 1940.

Macmillan's correspondence includes files of letters to his wife (1917-1936) on his war service and political affairs; personal and social letters (1923-1929); political correspondence, including several letters from McKenzie King (1926-1946); letters concerning McGill, including a number from Sir Arthur Currie and from Stephen Leacock (1920-1947); post-retirement correspondence on McGill and public affairs; and correspondence concerning his publications (1920-1960). There are also files of invitations to events at McGill and elsewhere.

The manuscripts fall into two categories: political speeches and literary manuscripts. Besides notes and texts for his own speeches, there are also texts of, and newspaper clippings about speeches written by Macmillan for Sir Arthur Currie and others (1920-1950). Drafts and typescripts of his literary works are supplemented by notes, clippings and correspondence.

The fonds primarily reflects Pappius’s activities as a researcher at the Montreal Neurological Institute-Hospital (MNI/H): both her experimental research as such and various support activities, including academic publication, coordination of research projects with colleagues, and acquiring funding. It also contains much information about her leadership of the Clinical Neurochemistry Laboratory. The fonds contains smaller amounts of documentation regarding her activities as a professor at McGill University, her administrative roles at the MNI/H, and her participation in professional organizations, which reflects the smaller place that those roles occupied in her professional life.

The period of time best documented in the fonds spans the early 1980s to Pappius’s retirement in 1995. Correspondence with colleagues, mostly though not exclusively work-related, contains relatively more material from Pappius’s early career; although, here too, most of the material dates from the 1980s and after.

The main document types in the fonds related to Pappius’s research activities are experiment worksheets and printed tabular research data. Many of the research-related files contain negatives of autoradiographies, with a smaller number of photographic prints. Correspondence can be found in many series besides series F (Correspondence), as much of Pappius’s work was collaborative in nature.

The fonds is divided into eight series: (A) Research, (B) Academic events, (C) Teaching, (D) Administrative activities, (E) Professional organizations, (F) Correspondence, (G) Personal collections, and (H) Visual documents.

Typed copies of the official and private correspondence, 1814-1821, held in the McCord Museum in the William MacKay Papers. They consist mainly consist of military records such as commissions, 1813-1814, correspondence between members of the British Indian Department, including Lt. Col. Robert McDouall and his description of the siege of Prairie du Chien, with reference to the Omaeqnomenew (Menominee), Hocak (Winnebago), and Meskwaki (Fox) warriors who fought alongside British forces, as well as to the Potawatomi leader Main Poc (referred to as Marpock), 1814-1815 and copies of correspondence of Capt. Thomas Anderson with Lt Col. Robert McDouall on military actions, supplies and Indian relations, 1814-1815. There is also a newspaper clipping about Alexander MacKay and the partnership agreement admitting William MacKay and David Mackenzie into the North West Company in 1796.

Kiang's papers cover the few years he was employed by McGill. His teaching materials include course outlines and examinations, as well as examination papers for a course in Oriental philosophy he gave at the University of Oregon Summer School in 1930. The administration of the Department of Chinese Studies is documented by requisitions and invoices for equipment and furniture, correspondence on library purchases, and letters regarding possible posts in the department, the curriculum, Kiang's salary and appointment, the Gest Chinese Library and general administrative matters. Kiang's personal files concern his work with the Hung Tao Society, his collaboration with Witter Bynmer, current events in China, and Kiang's publications and speaking engagements.

Very few of the McLeod papers actually concern the Observatory. However, his work for the railways and in Newfoundland is documented, as are his views on the education and employment of engineers. The basic record for the early part of his career is a diary kept from 1870 to 1875, regarding student days and early work on the Observatory. An essay, "Winter under canvas" (1868) describes an early surveying job, and a letter from his father (1872) inquires about his academic progress. His work for the railways is documented by three letters of recommendation, and two letters (one from Stanford Fleming) on the work of his colleagues in the West. The Newfoundland survey (1875) is described in McLeod's diary, a manuscript essay "Across Newfoundland" (1876), his printed reports and three letters. His work at McGill is represented by six letters (largely official acknowledgements of appointments), and McLeod's manuscript notes on McGill history. McLeod's concern with the engineering profession is reflected in two addresses on education and professional development, and copies of about a dozen letters to Sir Wilfrid Laurier (1906-1908), C.A. McGrath and E.F. Wurtele (1912), largely on the employment of engineers in the civil service.

Mintzberg's papers comprise student materials, office files, and papers relating to his publications. Student materials contain course notes from both the engineering (1956-1961) and management (1961-1968) phases of Mintzberg's education, as well as research notes and drafts for his doctoral thesis "The Manager at Work". His McGill office files contain reports, minutes and memoranda for various faculty committees (1968-1976); correspondence, particularly regarding the M.B.A. programme (1970-1976); course outlines (1968-1973); and files on his Ph.D. students (1974-1976) (Restricted). Papers relating to publications include research notes, working papers, and drafts of articles and books, as well as correspondence about his writings (1968-1978).
