Per Wikipedia Helen Battles Sawyer Hogg 1905 -1993 Was An American-Canadian Astronomer Who Pioneered Research Into Globular Clusters And Variable Stars. She Was The First Female President Of Several Astronomical Organizations And A Scientist When Many Universities Would Not Award Scientific Degrees To Women. Her Scientific Advocacy And Journalism Included Astronomy Columns In The Toronto Star "With The Stars" 1951-81 And The Journal Of The Royal Astronomical Society Of Canada "Out Of Old Books" 1946-65. She Was Considered A "Great Scientist And A Gracious Person" Over A Career Of Sixty Years. After Graduating From Mount Holyoke Hogg Received A Fellowship For Graduate Study At Harvard Observatory In The Fall Of 1926 With The Help Of Dr. Cannon.3 Once At Harvard Hogg Worked With Dr. Harlow Shapley The Director Of The Graduate Program In Astronomy. Hogg Received Her Master's Degree In 1928 And Her Doctoral Degree In 1931 Both From Radcliffe College As Harvard Refused To Award Graduate Degrees In Science To Women At The Time. For Her Advances In Astronomy Hogg Received Honorary Doctoral Degrees From Six Canadian And U.S. Universities Including Mount Holyoke College And The University Of Toronto. While Completing Her Doctoral Degree Hogg Taught Astronomy At Mount Holyoke And At Smith College. After Graduation She Moved To Victoria British Columbia Where She Began Research At The Dominion Astrophysical Observatory. Hogg Began Taking Photos Of Variable Stars With The 72-Inch Reflecting Telescope Cataloguing The Cyclical Changes In The Brightness Of The Variable Stars. At The Dominion Astrophysical Observatory Hogg Found 132 New Variable Stars In The Globular Cluster Messier 2. Hogg Published This Groundbreaking Work In Astronomical Catalogues That Are Still Used Today. Notably Hogg Accomplished All Of This As A Volunteer Assistant To Her Husband As The Dominion Astrophysical Observatory Would Not Offer Her A Job. In 1935 Hogg Moved To The University Of Toronto After Her Husband Had Received A Job Offer To Work At The David Dunlap Observatory.6 For Her First Year There Hogg Continued Her Work Photographing Globular Clusters Amassing Thousands Of Photographs Which She Used To Identify Many Thousands Of Variable Stars. She Published Catalogue Of 1116 Variable Stars In Globular Clusters In 1939 The First Of Three Catalogues She Completed With A Fourth In The Works At The Time Of Her Death. In Addition To Her Work On Variable Stars In Globular Clusters Hogg Used The Period-Luminosity Relationship Of Cepheid Variable Stars Discovered By Henrietta Swan Leavitt In 1908 To Enhance The Understanding Of The Milky Way Galaxy's Age Size And Structure. During The Late 1930S Hogg Became One Of The First Astronomers To Travel And Work Around The World To Advance Her Research As The Globular Clusters She Was Observing Were Best Seen From The Southern Hemisphere. From 1939 To 1941 Hogg Returned To America To Serve As The President Of The American Association Of Variable Star Observers 1939-1941 And The Acting Chair Of Mount Holyoke's Astronomy Department 1940-1941. Upon Returning To The David Dunlap Observatory She Took On Teaching Duties At The University Of Toronto Largely As A Result Of Male Staff Being Away Due To World War Ii.35 Retaining Her Position After The Men Returned From War Hogg Advanced To Assistant Professor In 1951 Associate Professor In 1955 Full Professor In 1957 And Professor Emerita In 1976 Upon Her Retirement.

"ON JUPITER AND ITS SATELLITES" by MARIA MITCHELL Professor of Astronomy at Vassar College. The first publication of the pioneering female astronomer's essay in "THE AMERICAN JOURNAL OF SCIENCE AND ARTS. Editors and Proprietors Professors James D. Dana and B. Silliman. Third Series. Vol. I. - Whole Number CI. Nos. 1-6. January to June 1871. And Vol. II. - Whole Number CII. Nos. 7-12. July to December 1871." 2 volumes bound in 1 as issued.

187197507New Haven: Printed by Tuttle Morehouse & Taylor 1871. 1871. Good. THE FIRST APPEARANCE OF THE ESSAY "ON JUPITER AND ITS SATELLITES" BY THE FIRST FEMALE ASTRONOMER IN THE U.S.A. - Octavo 8-1/2 inches high by 5-3/8 inches wide. The contemporary brown calf and marbled boards are detached but present and the spine has perished and is thus lacking. The text block is intact and tight. 978 pages in all with the pagination as follows: Volume I: pages i-viii & 1-484; and Volume II: pages i-viii & 1-480. Pages 327/328 are skipped in numbering as published which collates with the copy at the Peter H. Raven Library at the Missouri Botanical Garden. The volume is illustrated with 3 plates including one folding as well as several textual illustrations. Although the title page to the second volume indicates the presence of a map intended to illustrate E.W. Hilgard's article "On the Geological History of the Gulf of Mexico" page 391 the map is not here present if it ever was included. The endpapers are foxed and there is some light soiling to the title page of the first volume. The edges of the first few leaves are lightly darkened with a tiny spot of dampstaining to the top edge of those leaves. A very good tight copy which would be well worth rebinding. Most noteworthy is the first publication of Maria Mitchell's essay "On Jupiter and its Satellites" illustrated with a plate volume I pages 393-395.The first American scientist to discover a comet Maria Mitchell 1818-1889 was the first female astronomer in the United States. Working as the librarian of the Nantuckett Atheneum Maria Mitchell read through the day and spent her nights with her father at the observatory he built atop the Pacific Bank. Her discovery in 1847 of the comet which came to be named "Miss Mitchell's Comet" brought her international acclaim. She was awarded a gold medal by King Frederick of Denmark and elected as the first woman to join the American Academy of Arts and Sciences the following year. Mitchell traveled throughout Europe after leaving the Atheneum in 1856 meeting with astronomers the world over. She became involved and active in the anti-slavery movement and the suffrage movement and was subsequently instrumental in the formation of the American Association for the Advancement of Women. After the Civil War Mitchell was recruited to join the faculty at Vassar College where with a 12 inch telescope then the third largest in the US she specialized in studying the surfaces of Jupiter and Saturn. She made waves by encouraging her female students to come out at night for classes and celestial observations and brought in noted feminists including Julia Ward Howe to speak on political issues. Continuously championing the advancement of women she gave an important speech entitled "The Need for Women in Science" during the 1876 centennial. Mitchell was one of only 3 women to be elected to the Hall of Fame of Great Americans in 1905. She was also inducted into the National Woman's Hall of Fame in Seneca Falls New York. A lunar crater on the moon was named in her honor.Also worth noting is Professor L. Respighi's essay "On the Solar Protuberances" illustrated with a folding plate volume I pages 283-287.The Italian astronomer Lorenzo Respighi 1824-1889 was appointed appointed professor of mechanics and hydraulics at the University of Bologna. In that context his first works were mathematical and included a well-known memoir on the principles of differential calculus. Captivated by astronomy he succeeded Calandrelli as director of the astronomical observatory at the University of Bologna in 1855. After making observations on comets Respighi became director of the Campidoglio observatory in Rome where he devoted his attention to studying solar phenomena. His studies of the spectra of sunspots were particularly important as he observed the splitting of the absorption lines later described by Hale as the result of the Zeeman effect.Henry James Clark's essay "The American Spongilla a Craspedote Flagellate Infusorian" illustrated with a plate is here published on pages 426 through 436 of volume II.The American naturalist Henry James Clark 1826-1873 was a pupil of Asa Gray at the Cambridge botanical garden. He became an assistant to Louis Agassiz after graduating from Harvard and was professor of Zoology and of Natural History at numerous colleges and universities. From 1872 until his death in 1873 Clark was Professor of Veterinary Science at the Massachusetts Agricultural College in Amherst Massachusetts. He contributed to a number of periodicals and authored "Mind in Nature" 1863 and "Mode of Development of Animals" 1865. New Haven: Printed by Tuttle, Morehouse & Taylor, 1871. hardcover
