I half-a-teaspoonin I Women Doing Splendid Work In Astronomy Dr. Helen Hogg Tells Business Club of Contemporary Women Scientists As long ago as 1890 the Observatory at Harvard College had ten or fifteen women on its staff. To-day the numbers have been increased until there are now between forty and fifty women astronomers on the staff, though some of them are only part-time workers. This was one of the many interesting statements made by Mrs. Helen Hogg, Ph.D., late of Harvard a and Mount Holyoake Observatories, who, with her husband, is engaged in astronomical research work at the Dominion Astrophysical Observatory at Little Saanich Mountain, before the Victoria Business and Professional Women's Club yesterday evening. Speaking on "The Work of Contemporary Women Astronomers," Dr. Hogg recalled the outstanding contributions made to astronomical science by women, One of the most noted woman 85- tronomers of the day, according to the speaker, is Miss Annie Cannon, who has been at Harvard Observatory for forty years, and who was awarded the much-coveted gold medal of the American Association of Arts and Sciences In recognition of her work in the stellar spectra. Miss Cannon has classified thousands of stars into about eighty different subdivisions and has catalogued them. On one plate alone she classified 5,000 stars. Another important phase of women's work was in variable stars whose light varies periodically, and Dr. Hogg explained how tance and light of a star was determined with the assistance of charts and diagrams. Over 4,000 of these variable stars had been discovered by the women at Harvard. It was in this particular phase of astronomical observation that Miss Leavitt of Harvard had achieved renown. five years ago Miss Leavitt had found the period luminosity relation for the Cepheid variables, which had enabled the astronomical distances of millions of stars to be measured to-day. ONLY WOMAN RESEARCH DIRECTOR Miss Margaret Harwood of the Maria Mitchell Observatory in Nantucket,| United States, had the distinction of being the only director of a research observatory in the world, according to the speaker. Dr. Hogg illustrated her address with a series of unusually beautiful slides showing the structure of the Milky Way system with its planetary nebulae, all of the slides being made from plates obtained by women astronomers. Mrs. E. G. Maynard, the president, was in the chair and thanked the speaker for her illuminating address, which was followed with rapt interest. During supper Miss Bishop, accompanted at the piano by Miss Heale. sang very charmingly "'Goin' Home" and "Song of the Soul." It was announced that the annual meeting will be held on January 25, and an invitation was read to members from Seattle club to attend a gatherIng on January 26. A number of guests were welcomed at the meeting.
