Sad news about Dr. Ludden

Dear NM-Users, Regrettably, I am writing to let you know that Dr. Ludden passed away Tuesday evening, 30JUL2024. I was able to get there over the weekend prior to visit him and his family. During his wakeful moments we had some good scientific discussions. We talked a lot about NONMEM and how its functionality and utility has expanded since he retired. He was pleased to hear about the changes. He was surrounded by family for the days leading up to the end. They were all appreciative that I was able to get there and tell him (and them) how much he meant to all of us and the impact he had on our careers. I think memories of Dr. Ludden were characterized perfectly by Marc Gastonguay, "I am forever grateful for the positive impact that Tom had on my life and career, not to mention the tremendous, although often underappreciated, contributions he made to the disciplines of clinical pharmacology and pharmacometrics. His humble brilliance will be missed and fondly remembered." Steve Riley
