A tribute to
Mary Ellen Rudin
, editor of the Notices, invited the editors of this article to prepare a collective remembrance celebrating Mary Ellen Rudin’s life and work. In doing so, we asked several of Mary Ellen’s colleagues, collaborators, and students to each contribute a short piece. The choice of contributors was not an easy one, since Mary Ellen had a very rich mathematical and social life, to which this article can only attest. Space limitations meant that we could not accommodate all who would have liked to pay tribute to her, but we hope that they will find themselves, at least to some extent, represented by the reminiscences appearing here.
