I posted this note on the Societies for the History of Economics website when I heard the news that Mark Blaug had passed away on the 18th of November.
I would just like to say a few words about Mark. He apparently had a reputation for being hard and difficult but my own experience was of someone who was generous with his time and willing to help someone trying to think through difficult problems in the history of thought, and this was when I was merely a PhD candidate just beginning my work in the field. I had always been intimidated by his Economic Theory in Retrospect which even when I was at university, was the touchstone of what I thought it meant to be a true scholar. It set a standard I knew I could never hope to repeat. It is the only book from my university days that still sits on my shelf. I am very sorry to hear that he has passed away. Economics has lost one of its great historians.
