Western Slope Skies: Women in Astronomy

Ken Crawford

This is a continuing series on Women in Astronomy.  Today we meet Williamina Fleming.

One of the most famous Hubble Space Telescope images is of the Horsehead Nebula.  Did you know that it was first discovered in 1888 by Williamina Fleming?

Ms. Fleming was born in Scotland in 1857 and married James Fleming at age 20.  They moved to America in 1878.  Her husband abandoned her a few months later and she took a job as a maid for Edward Pickering, Director of the Harvard Observatory. Shortly thereafter, Pickering hired her as an assistant.  Supposedly Pickering fired a male assistant and said “My maid can do a better job than you”.  Whether he actually said this is un-substantiated; however, the statement proved profoundly correct.  

In 1886, the Observatory began the monumental task of photographing the entire sky and cataloging the stars.  Ms. Fleming supervised this effort.  In 1898, she became Curator of Astronomical Photographs, the first woman to be recognized at any observatory with a title of such importance.

Ms. Fleming developed a method of cataloging stars, based on their spectra, using certain letters of the alphabet.  While enhanced over the years, that system is still the primary technique for cataloging stars. She cataloged over 10,000 stars into what we know as the Henry Draper Catalog.  She published two books about stars.  She coined the term ‘white dwarf’ to describe the eventual fate of stars that are similar to our Sun.  

In 1906, she became the first American woman to be given membership in the Royal Astronomical Society.

Williamina Fleming died in 1911. She wrote the following in Scientific American, 1893: “While we cannot maintain that in everything, woman is man’s equal, yet in many things her patience, perseverance and method make her his superior. Therefore, let us hope that in astronomy, which now affords a large field for women’s work and skill, she may, as has been the case in several other sciences, at least prove herself his equal.”

A native Texan, Jeff was bitten by the Colorado "bug" after graduating from UT-Austin. He arrived in Paonia on the October full moon of 1978, and has been involved with KVNF since its earliest days. His first KVNF show was "Sunday Night Live," which featured live musicians performing in the original Garvin Mesa garage/studio.
