I'm not an historian of economics, but if there were a figure like Heilbroner in my own subdiscipline -- someone who benefitted the entire field by his efforts as a popularizer and who was regarded by (almost?) everyone as a decent human being -- I think I'd want to honor him or her and to elevate the discipline itself through the very giving of the honor. Would it be inappropriate to create a new prize named for Heilbroner? Going, perhaps, to someone with an exemplary record in spreading the history of economics to a wider audience and/or introducing numerous students to the subject? Robert Whaples
