John Kenneth “Ken” Galbraith, was a long-time Harvard faculty member. By long time, I mean he was a professor of economics for over half a century. A prolific author, with about 4 dozen books to his name, he also published more than a thousand articles and essays. Among his most famous works was the trilogy on economics: American Capitalism (1952), The Affluent Society (1958), and The New Industrial State (1967).
In The Harvard Guide to Influential Books: 113 Distinguished Harvard Professors Discuss the Books That Have Helped to Shape Their Thinking, we can find the books that influenced him.
In the preface to his brief response, he writes:
I do not urge economics; others will do that. Instead I urge the enjoyments and enlightenment to which the well-seasoned economist and citizen of the future are entitled and which have brought both pleasure and reward to me in the past.
Then he goes on to name the books that gave him enjoyments and enlightenment in point form.
