The Number Theory Foundation

About the NTF

The Number Theory Foundation (NTF) is an organization whose aim is to collect donations from supporters of number theory and to disburse these donations to encourage research and collaboration by helping to sponsor appropriate conferences and working to foster a spirit of cooperation and goodwill among the family of number theorists. The NTF does not seek to be the sole sponsor of projects, but rather to share in their support. Contributors of substantial donations to the NTF have the opportunity to decide which area or areas of number theory they wish to support and to specify how the support should be made: individuals, computational projects, conferences, or all of these.

Currently our available funds have been directed toward activities in computational and combinatorial number theory, as well as supporting general number theory conferences.

The NTF is at present a very small foundation and does not have the resources to singlehandly underwrite costly undertakings. We hope that grants from us can be used to help leverage support from other sources.

The NTF prefers that its conference grants be used for junior attendees who do not have other support, and that the grants be applied for and administered by the conference itself, not by individual participants. We also ask that grant funds be used only for the stated purpose, we are not able to cover any institutional overhead charges.

The NTF is a non-profit public charity. Contributions to the NTF are fully tax deductible in the U.S. Contributions may be made by a check to The Number Theory Foundation and sent in care of

Application Procedure

All applications for funding from the NTF should be accompanied by a brief summary (no more than one page) along with an outline of the budget and any other sources of funding. Applications for conference support should include the following information:

Applications should be submitted by email to All applications will be reviewed by the Board of Directors. The outcome of this review will be either a decision or a request for further information.

In Memoriam

Ronald L. Graham (1935-2020), who passed away on July 6, 2020, was one of the original directors of the Number Theory Foundation and an active member of the board through 2020. At various times in his career he was the president of the American Mathematical Society, the Mathematical Association of America, and the International Jugglers' Association. See his obituary in the New York Times for more information.

Richard K. Guy (1916--2020), who passed away on March 9, 2020, was a great friend, and supporter of the Number Theory Foundation from the beginning; he was one of the original directors and helped to guide the foundation for more than twenty years. See the MAA Focus memoriam article for some reflections on his remarkable life.

Barbara Selfridge (1951-2018), daughter of John Selfridge, was a feminist writer, playwright, actor, and activist. Over the years she generously supported The Number Theory Foundation. Her one-woman play Zero Tolerance: Sex, Math and Seizures documented her complicated relationship with her father.

Paul Bateman (1919--2012) was one of the original directors and an early contributor to The Number Theory Foundation. For more information see his University of Illinois memoriam, and his memoriam page at Celebratio Mathematica.

John Selfridge (1927--2010) founded The Number Theory Foundation. For more information, see the preface to the John Selfridge Memorial Volume of Integers, and also his obituary.

Ethel Rathbun (1932--2005) was the first executive administrator of The Number Theory Foundation. She is also warmly remembered as the administrator for the University of Michigan Mathematics Department. For more information see her obituary in the Ann Arbor News.
