The William Feindel fonds documents the research, writing, teaching, and various professional activities of William Feindel. Materials related to Feindel’s research make up the bulk of the fonds and cover his many research interests in the field of neurology as well as his interest in the history of medicine and the legacies of Wilder Penfield, William Osler, and 17th-century physician and neuroanatomist Thomas Willis. An entire series is dedicated to records related to Feindel’s role as the curator for the Wilder Penfield archives. The William Feindel fonds also documents his work for the Montreal Neurological Institute, his role as Acadia University’s Chancellor, and several professional appointments. A series of notebooks consists of Feindel’s notes on various research topics but also contains notes regarding personal matters. Along with the notebooks, a series that documents Feindel’s personal life includes materials related to his family, his years as a student, and a variety of souvenirs and books that he kept as part of his personal library.
