The College of Mechanics Baldwin went on to graduate study at Cornell University and became the first woman to receive a PhD in science in Physics from an American university. Her paper “A Photographic Study of Arc Spectra” was published in 1896 and is still available online: . Equipped with a doctorate, Baldwin nonetheless taught physics at the California School of Mechanical Arts, a vocational secondary school in San Francisco associated with UC Berkeley. Baldwin’s status as a married woman with two children, similar to that of other Berkeley women graduates in STEM of her era, would have been an obstacle to a position in higher education.
