Popular Science Monthly/Volume 35/August 1889/Obituary Notes
Maria Mitchell, a distinguished astronomer and professor in Vassar College, died in Lynn, Mass., June 28th, of disease of the brain, from which she had been suffering for about eighteen months. She was born in Nantucket, in 1818, the daughter of an amateur astronomer, and studied under her father and Charles Pierce. At eleven years of age she recorded the time of the beginning and ending of an eclipse of the moon. In 1847 she discovered the first of her eight comets. She was the first woman to be elected to the American Academy of Arts and Sciences; was a member and fellow of the American Association for the Advancement of Science; an LL.D. of Hanover and Columbia Colleges; and was actively interested in measures to elevate woman's work. She resigned her professorship at Vassar College in January, 1888, but no action was taken on her resignation, so that she still remained the titular incumbent.
