One of us (AG) has been fortunate in knowing the late F. Ann Walker pretty much all of his professional life. Her many talks on advanced NMR and EPR studies of heme proteins at national American Chemical Society meetings and at Gordon Research Conferences made a profound impact on me and the entire heme protein and model compound community. Her papers, review articles, and book chapters, likewise, survive as exemplars of scholarship. Add to that an exemplary record of service, perhaps most notably as long-time Associate Editor of JACS, and mentoring, and you have a rare role model who inspired multiple generations of bioinorganic chemists. Below are a few first-person reminiscences.
