The Glass Universe

Starred review from October 3, 2016
Acclaimed science writer Sobel (A More Perfect Heaven) casts much-needed light on the brilliant and determined women behind two historic revolutions in astronomy: one scientific, one professional. In the mid-18th century, astronomers employed human “computers” to scan glass photographic plates and perform calculations. Only the Harvard College Observatory, directed by professor Edward Pickering, hired both men and women as computers. The women there—including Williamina Fleming, Antonia Maury, Henrietta Leavitt, Annie Jump Cannon, and Cecilia Payne—earned far less than their male counterparts but were eager for the work. As Sobel explains, it was the only way they could do science. Their research led to both the creation of a catalogue of stars still in use today and groundbreaking discoveries in stellar composition, motion, evolution, and a reliable way to calculate interstellar distances. Sobel knows how to tell an engaging story, and this one flows smoothly, with just enough explication of the science. She also reveals the long hours the women worked and their constant search for funding as well as their triumphs of discovery and the eventual acknowledgment of their achievements by their peers and public. With grace, clarity, and a flair for characterization, Sobel places these early women astronomers in the wider historical context of their field for the very first time.

Popular science writer Sobel (And the Sun Stood Still, 2016, etc.) continues her project of heralding the many contributions of women to science.If you took an astronomy course in college, you learned a still-current classification system for the stars whose origins stretch back to the 1880s as well as a geography in which a star such as HD 209458--which "made news when modern detection methods located a planet in orbit around it"--finds its place in the star charts. Though the Henry Draper Catalogue bears a man's name, it was the work of the women he hired as "computers" who did most of the analysis that fueled it. Draper, an astronomer and technologist, funded that work, overseen by a Harvard scientist named Edward Charles Pickering, who thought it ungallant to have women scrambling about in the cold and dark with the telescopes but thought that "women with a knack for figures could be accommodated in the computing room, where they did credit for the profession." So they did, and Sobel's heroines, at 25 cents per hour, made signal contributions to observational astronomy. Henrietta Swan Leavitt, for instance, took on the Great Nebula in Orion, discovering hundreds of variables, while the indomitable Williamina Paton Stevens Fleming ran an efficient shop while making enough advances on her own that, largely overlooked in her own country, she was made an honorary member of the Royal Astronomical Society in 1906. Often, even as they made major discoveries, the "computers" of Harvard College Observatory left it to the males who ruled science to bask in their glory. More than recounting and celebrating the lives and work of these distinguished and decidedly unsung women, Sobel also provides insight into how basic science research is now supported, thanks to lessons learned in the military and commercial applications of once-arcane technologies--though, even after World War II and their contributions to it, women found it as difficult as ever to find scientific work. A welcome and engaging work that does honor to Sobel's subjects.

Sobel first came to our attention with "Longitude", the 1997 British Book of the Year, and achieved No. 1 "New York Times" best seller status a few years later with "Galileo's Daughter". Here she chronicles the contributions made by women at the Harvard College Observatory from the late 1800s, with the hire of recent graduates from the new women's colleges like Wellesley and Vassar, through the 1956 appointment of Dr. Cecelia Helena Payne to the astronomy department as the first ever female professor at Harvard. Their work largely entailed examination of the glass photographic plates that captured the stars each night (hence the title) and totaled a half million plates in the era Sobel studies.

Railroad heiress Anna Draper was introduced to a love of the stars by her husband, Dr. Henry Draper, whose stellar photography was recognized throughout the United States. After his death, Anna Draper wished to continue his work photographing stars and reached out to one of his many prominent scientific colleagues, Edward Pickering, a professor at the Harvard College Observatory. Henry Draper's work reflected the changes in the late 1800s in the field of astronomy as advancements in photography improved the quality of stellar images. As technology progressed, more people were needed to analyze and preserve the images. The Harvard College Observatory expanded their staff (previously only men) to include the wives and other family members of the astronomers working at Harvard; eventually graduates of women's colleges such as Vassar, Radcliffe, and Wellesley were employed as well. The women were originally hired as human calculators, but their roles grew to encompass cataloging the images as well as participating in the astronomical studies conducted by the male astronomers. Over time, the women's contributions to the field of astronomy ranged from identifying new stars to developing a stellar classification system that is still in use today. Relying on primary source materials such as letters and memoirs, Sobel crafts a story that illuminates the crucial role women played in the scientific community. VERDICT Teens interested in astronomy and the recent Hidden Figures will be fascinated by the work and discoveries made by these ambitious and talented women.-Lynn Rashid, Marriotts Ridge High School, Marriottsville, MD
