In Memory of John Brillhart
With a heavy heart, we bring you the news that West Coast Number Theory’s very first participant, John Brillhart, has died this year.
John passed away on May 21, 2022, at the age of 91.
A few years ago, we asked John to describe the origin of the meeting now known as the West Coast Number Theory conference. This is the message he sent in reply:
In January 1967, I got my PhD from Berkeley under D. H. Lehmer and then moved to Tucson, Arizona that fall to start teaching at the University of Arizona. That December at Christmas, I returned to Berkeley to visit my family, so the Lehmers and Robinsons decided to have a Christmas get-together in the form of an informal mini meeting with talks as well.
Dana Scott, Hansraj Gupta, and Don Knuth, who drove up from Stanford, came to the meeting. It was very pleasant. The following Christmas, when I again returned to Berkeley, the party/meeting was repeated; Emma Lehmer and Julia Robinson this time made cookies.
In August of 1969, there was a remarkable meeting at Oxford University on computational number theory to which a huge representation of number theorists came. There is a wonderful photograph of this meeting that is available on the internet. It was at this meeting that the Lehmers decided that they would make the Christmas meeting an annual affair, which they did the following Christmas. And thus, the meeting was founded, and though it has changed over the years, it has remained the same informal, pleasant venue that welcomes mathematicians, young and old, to come and talk about what they want.
John Brillhart is likely best known mathematically for his work on the continued fraction factoring algorithm with Mike Morrison, which is said to have ushered in the modern age of integer factoring methods.
John was also one of the original board members of the Number Theory Foundation, a non-profit organization that supports number theory events.
We will be honoring John Brillhart this year during the West Coast Number Theory conference Dec 15-19, 2022.

2021 Lehmer Prize Awards
We are pleased to announce the winners of the 2021 Emma and Dick Lehmer prizes, given to the organizing committee’s favorite talks of the conference. Since we were having an agonizingly difficult time picking just two excellent talks, and since we didn’t give out any awards during the pandemic pause of 2020, we decided to double the number of recipients this time around.
The 2021 recipients of the Lehmer Prize are:
- Shanna Dobson: Diamond L-Groups and Diamond Modular Curve
- Vaishavi Sharma: Arithmetic properties of the divisor function
- Johann Thiel: Solving the membership problem for certain subgroups of SL_2(Z)
- Sarah Arpin: Supersingular Elliptic Curve Isogeny Graphs with Level Structure
Congratulations to all our award winners, and we hope to see you in 2022!
