Mike Titterington (1945-2023)

Most sadly, I just heard from Glasgow that my friend and coauthor Mike Titterington passed away last weekend. While a significant figure in the field and a precursor in many ways, from mixtures to machine learning, Mike was one of the kindest persons ever, tolerant to a fault and generous with his time, and I enjoyed very much my yearly visits to Glasgow to work with him (and elope to the hills). This was also the time he was the (sole) editor of Biometrika and to this day I remain amazed at the amount of effort he dedicated to it, annotating every single accepted paper with his red pen during his morning bus commute and having the edited copy mailed to the author(s). The last time I saw him was in October 2019, when I was visiting the University of Edinburgh and the newly created Bayes Centre, and he came to meet me for an afternoon tea, despite being in poor health… Thank you for all these years, Mike!

Greg Bear (1951-2022)

Just heard that the science-fiction writer Greg Bear had passed away. I read [a French translation of] Blood Music in 1985 or 1986, and while I did not like the second half so much, I remember being impressed by the originality of the story when compared with classics like Asimov’s Foundation trilogy. (Little did I know that Bear would later contribute to the Foundation corpus by Foundation and Chaos, which I have not read to this day.) Later, much later, I read Hull Zero Three, again an original (if space-operatic) book, and Darwin’s Radio, which remains one of my favourite books in science fiction, if only because it is deeply grounded into science. Followed by Darwin’s Children this very summer. (I may have read Moving Mars as the story synopsis sounds familiar, but I am unsure…) A great writer, to whom I am grateful for all the gripping time spent on his page-turning books!

David Cox (1924-2022)

It is with much sadness that I heard from Oxford yesterday night that David Cox had passed away. Hither goes a giant of the field, whose contributions to theoretical and methodological statistics are enormous and whose impact on society is truly exceptional. He was the first recipient of the International Prize in Statistics in 2016 (aka the “Nobel of Statistics”) among many awards and a Fellow of the Royal Society among many other recognitions. He was also the editor of Biometrika for 25 years (!) and was still submitting papers to the journal a few month ago. Statistical Science published a conversation between Nancy Reid and him that tells a lot about the man and his amazing modesty. While I had met him in 1989, when he was visiting Cornell University as a distinguished visitor (and when I drove him to the house of Anne and George Casella for dinner once), then again in the 1990s when he came on a two-day visit to CREST,  we only really had a significant conversation in 2011 (!), when David and I attended the colloquium in honour of Mike Titterington in Glasgow and he proved to be most interested in the ABC algorithm. He published a connected paper in Biometrika the year after, with Christiana Katsonaki. We met a few more times later, always in Oxford, to again discuss ABC. In each occasion, he was incredibly kind and considerate.

Don Fraser (1925-2020)

I just received the very sad news that Don Fraser, emeritus professor of statistics at the University of Toronto, passed away this Monday, 21 December 2020. He was a giant of the field, with a unique ability for abstract modelling and he certainly pushed fiducial statistics much further than Fisher ever did. He also developed a theory of structural  inference that came close to objective Bayesian statistics, although he remained quite critical of the Bayesian approach (always in a most gentle manner, as he was a very nice man!). And most significantly contributed to high order asymptotics, to the critical analysis of ancilarity and sufficiency principles, and more beyond. (Statistical Science published a conversation with Don, in 2004, providing more personal views on his career till then.) I met with Don and Nancy rather regularly over the years, as they often attended and talked at (objective) Bayesian meetings, from the 1999 edition in Granada, to the last one in Warwick in 2019. I also remember a most enjoyable barbecue together, along with Ivar Ekeland and his family, during JSM 2018, on Jericho Park Beach, with a magnificent sunset over the Burrard Inlet. Farewell, Don!
