John Maynard Keynes - A great investor
John Maynard Keynes Many readers have likely heard of John Maynard Keynes, arguably the most influential economist of the 20th century. Keynes is most famous for debunking the old theories of classical economics and developing a systematic way of analyzing macroeconomics with consideration of politics and philosophy. Yet, I'll bet that only a few readers would know that he was also one of the top investors of all time. Investing wasn't Keynes' main job and he wasn't exactly a money manager so his investing activities aren't widely known.
