Cherie was a friend for almost a quarter of a century: She started with Barry at Caltech in 1988, and I was then a frequent summer visitor throughout and a bit beyond the 1990's. Cherie was unique in so many respects: She masterfully ran Barry's office (no easy task given Barry's extraordinary active life in many aspects of science) , she was always there for his students and postdocs, and she made visitors feel at home at Caltech. She had extraordinary intellectual capacities: Although without mathematical training, as far as I know, when proofreading manuscripts, her pattern recognition ability was just incredible. She spotted any irregularities in formulas, missing parentheses, etc., and more often than not confounded Barry's co-authors with errors they should have found, but didn't. I learned quite a few subtleties regarding the English language from Cherie, and my own style of writing most certainly profited from her kind comments.  As a frequent collaborator of Barry's, Cherie and I often worked together over the years. Preparing Barry's 60th birthday bash at the end of March of 2006 (http://math.caltech.edu/mp2006conf.html) was definitely the crowning achievement of our collaboration. As I said at the very end of the conference banquet, no one, absolutely no one, could have pulled this off without Cherie's help. She was the glue that kept everything together and under control. However, it did not end with organizing the conference. As a second major conference related project we planned a two-volume Festschrift that was to represent a panorama of Mathematical Physics, focusing on areas of Barry's research (http://www.ams.org/bookstore-getitem/item=PSPUM-76). It was quite an undertaking given the amount of articles (and the strong personalities of authors involved) that had to be processed. Cherie did such an extraordinary job in putting the conference proceedings together that the idea arose to make her one of the editors of these proceedings. To the delight of the remaining editors, she happily accepted the proposal. She most definitely raised the bar and set new standards in her profession. Whenever I visited Caltech, we enjoyed discussions after hours, and at occasional joint lunches. We often talked politics and typically agreed,  being partial to the same end of the political spectrum; we also talked a lot about sports, football in particular, and since she liked the Patriots and I the Colts, she got the better of me almost every year (but not every year!). In fact, we had numerous sports bets that I happily lost, after all, they gave me a convenient excuse to invite her to lunch. Cherie typically played along, but she was never fooled and knew precisely what I was up to. We also frequently shared little secrets about people we thought we knew sufficiently well.       Last fall I noticed that our e-mail contacts diminished and we even missed out on our annual bet on the 2013 Superbowl. I misinterpreted this as her just being too busy, little did I know. Her diagnosis, and the events unfolding subsequently, came as a shock. While Cherie will be terribly missed by her many friends all over the globe, she will live on in our memories; she most definitely does in Gloria's and mine.   Fritz Gesztesy (University of Missouri, Columbia)
