These are a few of "the Harvard Computers," a group of about 80 women who worked at the Harvard Observatory at the turn of the century. Before the days of Bill Gates and OS updates, the word “computer” was used (as far back as the 17th century) to describe a person who performs calculations. The Computers were hired by the Observatory’s director, Edward Charles Pickering (back row), to help catalog and analyze thousands of early photographs of the night sky.
The Computers worked six-day weeks and earned between 25 and 50 cents an hour. Employed as technicians, their tasks included measuring the brightness of stars and analyzing spectra to determine the properties of celestial objects. Aside from their clerical bookkeeping, however, many of the women were fascinated with astronomy and made discoveries of great importance. #tbt #throwbackthursday
