Francisco José Ynduráin (1940-2008) died on 6/6/2008. He was one of my professors at the Universidad Autonoma de Madrid. He taught, among other things, "Advanced Quantum Mechanics," one of the courses I took during my fourth year. He wrote some fun, high-quality popular science/physics books (unfortunately they haven't seen translation into English) which I enjoyed on the side. His dry-witted, sarcastic, no-nonsense classes agreed well with me, which was more I can say for some of the other courses I slogged through at the time.
Four of his books stand on the shelf before me. He signed two of them (a request I delicately timed until after I'd found out I had passed his course). The signature is dated 6/27/2002, six years ago almost to the day--though it seems more like a lifetime away now.
His major research contributions were in the field of QCD. Here's an advanced textbook on the subject he wrote, now a standard reference. And here's a link to 53 of his research papers, available online.
