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 of the project and an outline of the budget, including any other sources of funding. This information should not exceed one page in length and should be submitted by email to Proposals will be considered as they are received on a rolling basis; there is no application deadline.

All applications will be reviewed by the Board of Directors. Quick funding decisions may be made in cases where the requested amount is small (under $1000) or the project summary contains information the Board deems sufficient to render a decision.

Following a positive review of the project summary applicants may be invited to submit a more detailed funding proposal. This second application, which should also be submitted electronically should include the following information.

Selected Past Grants

NTF was a partial sponsor of the following meetings and events:

In Memoriam

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.

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.
