Phoebe Waterman Haas (September 20, 1882 1967) was one of the earliest American women to be awarded a doctorate in astronomy (1913). While her formal professional career ended upon her marriage, she contributed as a citizen scientist, volunteering for the American Association of Variable Star Observers (AAVSO). The Phoebe Waterman Haas Public Observatory was supported by donations from her family and is named in her honor.
