Records in this series document Dr. Hogg's involvement in numerous associations relating to the study of astronomy. The series, comprised mainly of correspondence, memoranda, reports, membership lists, newsletters, agenda and committee minutes, documents the various positions of authority she held in the leading national and international astronomical and scientific organizations. They cover a twenty-five year span including:
Program Director for Astronomy, United States National Science Foundation (1955-1956); president of the International Astronomical Union Subcommission on Variable Stars in Star Clusters (1955-1961); president of the Royal Astronomical Society of Canada (1957-1959); first woman president of the Physical Sciences section, Royal Society of Canada (1960-1961); president of the Royal Canadian Institute (1964); Councillor of the American Astronomical Society (1965-1968); first president of the Canadian Astronomical Society (1971-1972); honorary president of the Toronto Centre, Royal Astronomical Society of Canada (1972-1977) and honorary president of the Royal Astronomical Society of Canada (1977-1981).
The series also serves to document the wider activities of these organizations in addition to simply shedding light on the activities of Dr. Hogg alone. Notably, council and committee minutes strongly document the workings of the Toronto Centre of the R.A.S.C. between 1961-1986, the R.S.C. between 1955-1985 and the R.C.I. from 1954-1968. The activities of the IAU are also well represented. In particular, a series of reports and memoranda between 1952-1981 highlight the workings of Commission 27 on Variable Stars. Related records outlining the activities of these professional organizations can also be found in the General Professional Correspondence Series (Series I).
