Read at the 2005 HES Conference by Don Moggridge, chair of the Spengler Prize Committee:  
  
I have an obligation to be brief this evening in awarding the Spengler Prize for the best
book in economics. The book is a history of the development of and relationship between
two disciplines in the twentieth century -- mathematics and economics. It is a history
with a strong biographical, and even an autobiographical twist. It benefits from a
somewhat wider disciplinary perspective than most works in the history of economics.
Finally, unlike most books in the subject, it even has charm. I am referring, of course,
to Roy Weintraub's _How Economics Became a Mathematical Science_ published by Duke
University Press.
  
The committee consisted of me, Joe Persky, Steve Horowitz and John Whitaker.
