Early life

Anne Sewell Young was born in Bloomington, Wisconsin, on January 2, 1871, to Reverend Albert Adams Young and Mary Sewell. Young came from a family with a strong tradition and connection in astronomy. Her grandfather, Professor Ira Young, held the Chair of Natural Philosophy and Astronomy at Dartmouth College, and her great-grandfather, and uncle were all respected Dartmouth astronomers, and her great-uncle even designed the observatory at Dartmouth.

(AAVSO) and in 33 years contributed over 6,500 variable star observations to the organization. She was elected the organization's President in 1923. One of the highlights of her career was organizing a special train to transport students from Mount Holyoke and other women’s colleges to a golf course in Connecticut to observe the total solar eclipse of January 24, 1925. The next few years were Miss Young’s last before retirement in 1936. She continued her usual routine of courses, carrying out observations and speaking to amateur astronomy groups. Her last annual departmental report lamented the fact that since students were no longer required to take mathematics, there was an increasing reluctance among many to take anything involving figures. And she concluded by modestly saying that though she had always fallen short of what she hoped to accomplish, what she had achieved was largely due to the support of her co-workers. She was delighted to be able to leave the department in the capable hands of Alice Farnsworth. In June 1936, Young retired, at the age of sixty-five, and became Professor Emerita. She was succeeded by her former student, Alice Hall Farnsworth, as director of the Williston Observatory. Young moved to
