Mary Anna Palmer Draper

A glass plate had to be prepared before a star could be photographed. In the Drapers’ observatory, Anna’s work included coating those plates and keeping the observing records while Henry operated the telescope. The division of work matters. A photograph credited to her husband could depend upon her technical competence, and the scientific partnership preceded the much better remembered generosity of his widow.

Born Mary Anna Palmer in 1839, she belonged to the wealthy New York Palmer family. Her marriage to the physician and astronomer Henry Draper in 1867 joined financial resources to a household already steeped in experimental science. Their Madison Avenue residence accommodated a laboratory, lectures, and scientific gatherings; summers brought them to the observatory at Hastings-on-Hudson. The domestic establishment was also a place of work. In 1872 their observational partnership produced a photographic record of Vega’s spectrum, helping establish photography as a means of studying the physical constitution of stars. [2,3]

Anna participated in the construction of their improved telescope, including the labor of finishing its mirror. She accompanied the 1878 eclipse expedition to Wyoming. These activities belong to the history of scientific practice, rather than to a decorative account of a wife taking an interest in her husband’s profession. Access nevertheless depended on extraordinary advantages: money, property, instruments, and admission to a circle of established scientists. Her life demonstrates how those advantages could support a woman’s serious participation outside a salaried university appointment. [1,2]

Henry’s death in 1882 changed the form of her involvement. She transferred instruments and observational materials to Harvard and supported the continuation of the work under Edward Charles Pickering. The Henry Draper Memorial, established in 1886, financed the classification of stellar spectra. Anna followed its progress, corresponding with the observatory and visiting it. The project employed women whose expertise deserves its own recognition, including Williamina Fleming, Antonia Maury, and Annie Jump Cannon. Patronage made their work possible without making their discoveries the patron’s property. The memorial bore Henry’s name, while its survival depended upon Anna’s decisions and resources. [1,2]

Her interests extended to collecting antiquities. The New York Public Library’s joint Draper papers preserve correspondence concerning ancient objects as well as astronomy and family affairs. That evidence opens another inquiry into how a wealthy American woman assembled knowledge and possessions from distant cultures. The objects’ individual acquisition histories require examination before her collecting can be described more fully.

Within the Constellation, she is Eva Palmer-Sikelianos’s aunt, identified in Artemis Leontis’s family account as leaving Eva $25,000 in 1914. This is a documented family route to Natalie Barney through Eva; a personal relationship between Anna and Natalie has not been established. Anna’s independent importance lies in the making and financing of scientific knowledge. Her inclusion enlarges the archive’s account of what women could do with inherited wealth, beyond the literary salon or artistic household.
