Happy Birthday Annie Jump Cannon

Jascin N. Leonardo Finger • December 12, 2016

Yesterday was the birthday of Annie Jump Cannon.  In honor of her birthday, I am re-posting a blog I wrote last year.

A few weeks ago, Annie Jump Cannon was the featured Google “doodle.”  Google featured Maria Mitchell as the doodle a few years ago to celebrate her birthday and has been doing a good job of featuring well-known and lesser-known woman who have made a difference in our world.


Annie Jump Cannon was among the founding members of the MMA but she was also instrumental in the development of our astronomy program.  With a growing desire to further develop a fledgling astronomy program in 1906, the MMA began a dialogue with Harvard University’s Observatory and its director, Edward Pickering, Ph.D.  The connection to Harvard was to become essential to the success of the beginning years of the Maria Mitchell Observatory and continued a legacy of friendship and work – Maria Mitchell and her father worked with the Bonds who once ran the observatory at Harvard and the families were close friends.

Besides his advice and assistance, Pickering asked a member of his staff, Annie Jump Cannon to advise and assist the MMA.  This “provided an indispensable collaboration for Nantucket astronomy” with Cannon spending two weeks on the island in both 1906 and 1907 lecturing and teaching.  While back at Harvard, she continued to teach the students on Nantucket by mail.  Cannon would go on to be recognized as the leading woman astronomer of her generation and also as the founder of the astronomy department at the MMA.


Completed in 1908, the Maria Mitchell Observatory now was in need of a permanent astronomer.  An Observatory Committee was developed and chaired by Annie Jump Cannon.  From 1909 through 1911, the Association was able to employ an astronomer to teach classes, observe, provide lectures, and open the observatory for public observing for approximately a month each summer.  As the demand grew, the MMA realized that a more extensive program was needed and the Astronomical Fellowship Committee began to raise funds for an Astronomical Fellowship Fund.  With the support of many generous donors and a matching gift from Andrew Carnegie, by 1911 the MMA had the funds it needed to support  the fellowship and began its search for an astronomer who would conduct research and provide lectures, classes and open nights for the public from mid-June through mid-December.  The fellow would spend the remainder four months in research and study – every fourth year a full year of study would be spent in an American or European observatory.


With Pickering, Cannon developed the Harvard Classification Scheme, an attempt to organize and classify stars by temperature.  She was one of many women whom Pickering hired to reduce data and carry out astronomical calculations.  She would go on to become the Curator of Astronomical Photographs at Harvard.  She received a regular Harvard appointment but just two years before she retired – she was named the William C. Bond Astronomer.  Today, there is the Annie Cannon Prize which is awarded to women astronomers who have made outstanding contributions in astronomy.

10mo 1, 1847. {October 1, 1847} This evening at half past ten Maria discovered a telescopic comet five degrees above Polaris. Persuaded that no nebulae could occupy that position unnoticed it scarcely needed the evidence of motion to give it the character of a comet. From the journals of William Mitchell, father of Maria.

The Nantucket Maria Mitchell Association (MMA) announces that its annual Aquarium Release Day will take place on Saturday, October 10, 2026 from 10am - 12pm at the MMA Aquarium at 32 Washington Street. A sensory-friendly half hour will be offered from 9:30 – 10am. Join MMA staff to help the staff release this season’s Aquarium inhabitants back into the ocean. This community event is FREE to the public and a great opportunity to learn and celebrate the marine life that lives in the waters of Nantucket Island. The MMA Aquarium is dedicated to educating the public on the importance of biodiversity in our unique marine ecosystems found here on Nantucket. Each summer, the MMA Aquarium Manager, Chelsea Petrik, as well as her team of dedicated college interns and volunteers, explore the shores of Nantucket to find and document an assortment of over 7,500 individual marine animals, most of which are recorded and released. They snorkel, seine, and beachcomb to collect over 300 different marine animals. The animals are studied and cared for at the Aquarium so that the MMA can help people to learn more about these important marine organisms. Roughly seventy different species are featured at the Aquarium throughout the season. Local fishermen also provide the Aquarium with species they come across in their nets and at the end of their lines. Pre-registration is encouraged. Register at the link below: https://112458a.blackbaudhosting.com/112458a/2025-Aquarium-Release-Day-10Oct2026 The Maria Mitchell Association is a private non-profit organization. Founded in 1902, the MMA works to preserve the legacy of Nantucket native astronomer, naturalist, librarian, and educator, Maria Mitchell. 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. ###
