Sad to hear that Michael Atiyah has died. I studied many of his papers, and I enjoyed his classical "Introduction to commutative algebra" (which is by no means an introduction to the field). Also I had the honor to meet him several years ago in person. He had a kind and humble character, and by no means I felt I was discussing mathematics with one of the best mathematicians of the previous century. He was always lowering his level to match mine. He explained everything clear and he gave good advice that helped my career in many ways. Thank you, and requiescat in pace.
