J. K-Theory 8 (2011), 1–1 ©2011 ISOPP doi:10.1017/is011007014jkt163 Homage to Daniel Gray Quillen Daniel Gray Quillen passed away on April 30 of this year, after a long illness. More than anyone else, he was responsible for creating the subject of algebraic K-theory as it is pursued today, and for demonstrating its power and elegance. He also made fundamental contributions to many other aspects of mathematics: rational homotopy, model categories, formal groups, and cyclic homology, to mention a few. All of the ideas he has developed will survive him and give him the stature of a great mathematician of the 20th century. Many mathematicians including all of the members of our Board were greatly inspired and influenced by his vision, his teaching, and his writing. As editors devoted to a subject that Quillen largely created, we are highly appreciative of his crucial support for the journal ‘K-Theory’ and its successor, the ‘Journal of K-Theory’, and of all he has done for our area of mathematics. He will be greatly missed and fondly remembered.
