Dear all I would like to thank life for having met Thomas Streicher and having found in him a unique expert in solving problems in type theory with categorical methods. In particular, as a last thing of collaboration, I am very grateful to him for joining us in organizing the workshop on Doctrines and Fibrations, dedicated to Lawvere, in May 2023 in Padova https://events.math.unipd.it/WDF2023/#com. Deep condolences to Eva. Milly On 03/01/25 10:04, Oosten, J. van (Jaap) wrote: I just received information that Thomas Streicher passed away yesterday. Thomas fell ill last September, when he could not attend Pino Rosolini's retirement party due to pneumonia; then it turned out he has metastases in the lungs from a pancreatic cancer. After several chemo treatments his situation suddenly worsened, and yesterday he died, peacefully, without pain. Thomas was 66 years old. In Thomas, we mourn a logician and category theorist of exceptional calibre. Let me just recall that in 2011, during an Oberwolfach meeting, Vladimir Voevodsky praised Thomas' work on type theory as a paradigm of precision. But I personally mourn a friend. A warm person with many interests. I wish strength to his wife Eva, and his family.
