Dear Prof. Dr. Joseph Polchinski:

When I finally read your 1998 work, Quantum Gravity at the Planck Length [PDF], I was quite taken back.  Fascinating. For me, it is a most important contribution.

First, you were an early adopter! You took the Planck Length seriously! As a result, I have included a couple of brief references to your work here:

Thank you for your legacy of work and for all your recent reflections about the meaning and value of life: “I’m sorry that no one has gotten rid of the firewall, but please keep trying.” It is so endearing. Congratulations and thanks again for your constant search.

Most sincerely,

Bruce

Footnote: While writing this note, I continued my search of this scholar’s writings. There are 150 Polchinski articles within ArXiv alone. Then I learned that David Gross presented his last two lectures for him (https://arxiv.org/pdf/1512.02477.pdf and the follow-up https://arxiv.org/pdf/1601.06145. Then I learned he had died of brain cancer on February 2, 2018.
