Bell Canada Directorship

This series concerns Dr. Hogg's tenure as a member of the Board of Directors of Bell Canada (1968-1978) and her participation in, and chairmanship of its Social and Environmental Affairs Committee (1973-1978).

It consists primarily of general company related correspondence and memoranda which outline aspects of the workings of this major corporation over a ten year span, and the minutes and correspondence of the Social and Environmental Affairs Committee which she chaired from 1974-1978. The files also include several company-sponsored reports on various topics.

Advisory Committee on Science and Medicine of the Canadian Corporation for the 1967 World Exposition

Includes mainly copies of minutes, reports, agendas and correspondence of the Advisory Committee on Science and Medicine - EXPO, of which Dr. Hogg was an active member. There are also copies of speeches given by EXPO officials. Much of the papers relate to the development of "Themes" including storylines and exhibit designs.

Interfiled with copies of minutes and reports, is some original correspondence between Hogg and members of the committee which documents, to some degree, her particular role in the committee. The most extensive original material relates to her role as chairman of one of the lectures given as part of the Noranda Lecture Series. Included is correspondence, drafts for her introductory note, and progress reports of the series. The lecture series itself, sponsored by Noranda Mines, featured a host of international scientists, including Nobel Prize Laureates and was attended by specially invited audiences during EXPO '67.

Mount Holyoke Papers

In 1930-31, while working on her doctorate degree, Dr. Hogg taught astronomy at her alma mater, Mount Holyoke College. A decade later after following her husband to Canada, she returned to Mount Holyoke for a one-year appointment as Acting Chairman of the Astronomy Department. Records in this series which include lecture and lab notes, course outlines, tests and grades document her teaching activities in these early years of her career and supplement records found in Series 6.

University of Toronto. Department of Astronomy

This series documents Dr. Hogg's role as a member of the Department of Astronomy, especially her responsibilities as a teacher. Included are attendance lists and grades, laboratory exercises, term papers (1963-64), tests and examinations, and lecture notes. There is also reports and related correspondence showing Hogg's participation on Ph.D. Oral examining boards as well as a file of correspondence relating to the evaluation and recommendation of students and graduates of the Department.

Apart from records that relate directly to Dr. Hogg's teaching function there are also some records related to general administrative issues. Among these are files containing progress and work reports, requests for grants to the National Research Council, correspondence on Dr. Hoggs' salary and tenure status as well as general issues at the David Dunlap Observatory.

Arrangement is by type of record, following as described above.

Research Notes

This is a series comprised of research notes and data relating to specific projects or articles as well as notes taken by Prof. Hogg at various lectures and seminars. Filed at the end are some miscellaneous files containing notes with little or no identification. Arrangement is chronological, with the research notes superseding the seminar notes.

File B1994-0002/050(02) contains notes on a symposium by G. de B. Robinson, Institute of Technology, on the responsibilities of the Canadian University. Also contains notes on a seminar by J.T. Wilson on “Recent Physical and Geological Evidence Leading to a New Theory of Continental Drift” 1963

Star Cluster Files and Index Cards

The Star Cluster files, assembled over her 40 years as an astronomer, represent the core of Dr. Hogg's research in a field for which she is an authority and from which many of her published articles were derived. The files are variously comprised of raw data, calculations, correspondence, draft and published articles relating to specific globular clusters. Prints from photographic plates also accompany some files . Most files are titled according to the New General Catalogue number, e.g. NGC 6626, of the star cluster and are arranged numerically following Dr. Hogg's own filing system.

A set of ten boxes of bibliographic index cards accompanies the Star Cluster Files. Cards in boxes seem to relate to specific subjects ie. external galaxies, variables in clusters, interstellar absorption. Boxes /044 - /048 are arranged more or less chronologically by the date of the bibliographic references. All were used for various editions of "A Catalogue of Variable Stars in Globular Clusters". Box B1994-0002/048 appears to relate specifically to references used in "A of Bibliography of Individual Globular Clusters" and its supplement. Index cards in box B1994-0002/049 do not appear to be bibliographic references but rather relate information on specific star clusters and are arranged by NGC number.

Photographs have been left in their original files because of their immediate association with the research materials. It was feared that removal of these photos from individual files would obscure the meaning of both the research in the file and the photographs themselves.
