The Ruth Lyttle Satter Prize in Mathematics, also called the Satter Prize, is one of twenty-one prizes given out by the American Mathematical Society (AMS).[1] It is presented biennially in recognition of an outstanding contribution to mathematics research by a woman in the previous six years.[2] The award was funded in 1990 using a donation from Joan Birman, in memory of her sister, Ruth Lyttle Satter,[3] who worked primarily in biological sciences, and was a proponent for equal opportunities for women in science.[4] First awarded in 1991, the award is intended to "honor [Satter's] commitment to research and to encourage women in science".[5] The winner is selected by the council of the AMS, based on the recommendation of a selection committee.[5] The prize is awarded at the Joint Mathematics Meetings during odd numbered years, and has always carried a modest cash reward. Since 2003, the prize has been $5,000,[5][6] while from 1997 to 2001, the prize came with $1,200,[7][8] and prior to that with $4,000.[9] If a joint award is made, the prize money is split between the recipients.[7]
Dusa McDuff was the first recipient of the award, for her work on symplectic geometry.[10] A joint award was made for the only time in 2001, when Karen E. Smith and Sijue Wu shared the award.[7] The 2013 prize winner was Maryam Mirzakhani, who, the following year, became the first woman to be awarded the Fields Medal, which is considered to be the highest honor a mathematician can receive.[11][12] She won both awards for her work on "the geometry of Riemann surfaces and their moduli spaces".[13] The most recent winner is Ana Caraiani, who was awarded the prize in 2025 "for contributions to arithmetic geometry and number theory: in particular, the Langlands program.".[14]
"for her work (much of it joint with Maksym Radziwiłł) opening up the field of multiplicative functions in short intervals in a completely unexpected and very fruitful way..."
