Fonds documents Dr. Antonio Cantero's professional activities, especially his cancer research. The fonds contains correspondence, notes, reports, printed matter, slides, photographs and films.

File consists of reproductions of photographs and negatives depicting staff and students of the Bishop's Medical and Dental Faculty, originally taken by Elizabeth Hearn Milner. These images were included in her book, "Bishop's Medical Faculty, Montreal, 1871-1905: including the affiliated dental college, 1896-1905," published in Sherbrooke, Quebec, in 1985 and available in McGill's library catalogue.

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.

Collection consists chiefly of photographs of Harold N. Segall, Assistant Professor of Medicine at McGill (1949-1960) and President of the Canadian Heart Foundation, Montreal Cardiac Society, and the Quebec Heart Foundation, as well as his parents, brother Jerry Segall, friends, and colleagues. Photographs depict Segall's childhood and early career. There are also some photographs and textual records relating to Segall's association with professional societies and Montreal hospitals, namely the Canadian Heart Association, Montreal General Hospital, and the Jewish General Hospital.

Fonds documents Dr. H.E. MacDermot's medical-historical activities. The fonds contains newspaper clippings, manuscript notes, photographs, lectures notes, and a draft of The MGH, the Years of Change.

Fonds consists of photographs and other items that document the early career of Isadore Hirshberg while studying medicine at McGill University from 1909-1914, including 60 album-sized photographs, a framed group photograph of Hirshberg and Montreal General Hospital residents, Hirshberg's framed provincial medical certificate, and two certificates of residency. Subjects include Hirshberg and classmates; campus and student life; photographs of staff, doctors, and nurses in hospital settings, including two photographs of John McCrae at the Alexandra Hospital; and various views of McGill medical buildings and hospitals, including the new medical building at the time of construction in 1910, the Royal Victoria Hospital around 1910, and the Western Hospital in 1913. Two photographs features the medical school janitor James "King" Cook, a fixture of the school and a favorite with the students from the late 19th through the early 20th centuries. His wife was Frank Buller's housekeeper during Osler's time. Fonds also includes a large framed group photograph, Resident Medical Staff/Montreal General Hospital/1914-1915 by Wm. Notman & Son and Hirshberg's Quebec medical license issued by the College of Physicians and Surgeons of Quebec and dated July 1914. Descriptions of the photographs where present are in Hirshberg's hand except in cases in which there were additional descriptions in the album. These were copied in pencil on the verso of the related photograph.

Fond contains solely glass slide negatives. Many slides depict the McGill campus between the years 1918-1921, including the Strathcona Medical Building, as well as the Royal Victoria Hospital. Other subjects include street scenes taken in Montreal after the end of the First World War and the Lockharts' family life during the early 1920s.

The collection contains a photo album of classmates and Annie Hall, and three diplomas McGill MD, CM 1891, Ontario College of Physicians and Surgeons, 1891, and the Quebec College of Physicians and Surgeons 1892.

The collection contains the Holmes Gold Medal, photographs, certificates, a poem, letters, newspaper clippings and memoirs.

File contains 14 slides that detail the life and work of Ramon Cajal. Each slide includes a detailed description and features images such as his portrait, birthplace, medical school, monument, commemorative stamp, a street named in his honour, and his grave in Madrid.
