NANTUCKET, MA— The Nantucket Maria Mitchell Association (MMA) welcomes Susan Vizurraga for a discussion of her book Williamina Fleming, Astronomer, an imagined memoir. As one of the Harvard College Observatory’s (HCO) women computers Williamina Fleming led a fascinating life. She was, an immigrant, a 

working mother, and an astronomer and her story will be brought to light in this engaging presentation on the remarkable legacy of a woman who helped transform modern astronomy from behind the scenes. Through Fleming’s own imagined voice, Vizurraga explores Williamina’s journey from domestic servant to internationally respected scientist, her pivotal role in classifying stellar spectra, and her quiet perseverance in a male-dominated field. This talk celebrates Williamina Fleming not only for her scientific achievements, but also for her resilience, curiosity, and lasting impact on how we understand the stars. This free event will be held via Zoom on Wednesday, February 18, from 7–8 pm.

Susan Vizurraga is the author of the historical fiction novel-in-verse Williamina Fleming, Astronomer, an imagined memoir based on the life of the real-life Scottish immigrant who began work as a maid, joined the HCO as one of many women computers, and became the discoverer and curator of stars. A former middle school teacher and university instructor, Vizurraga is the author of the picture books Our Old House (a Junior Library Guild Selection) and Miss Opal’s Auction (a multi-generational selection of the National Council for the Social Studies). She is a volunteer docent at the Georgia Museum of Art and a poll worker with her local elections board. She lives in rural southern Oconee County, Georgia.

The Maria Mitchell Association was founded in 1902 to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. After she discovered a comet in 1847, Mitchell’s international fame led to many achievements and awards, including an appointment as the first professor of astronomy at Vassar College. Maria Mitchell believed in “learning by doing” and today that philosophy is reflected in the MMA’s mission statement, programs, research projects, and other activities. The Maria Mitchell Association operates two observatories, a natural science museum, an aquarium, a research center, and preserves the historic birthplace of Maria Mitchell. A wide variety of science and history-related programming is offered throughout the year for 

people of all ages.
