Milton Friedman was one of the most influential economists of the 20th century, right alongside John Maynard Keynes. His work pushed economic thought toward free markets in the 1970s and 1980s. His passionate defense of capitalism and economic freedom had global appeal right through the present day. As such, the closing decades of the 20th century have been termed "The Age of Friedman," yet commentators have sought to hold him responsible for both the rising prosperity and rising inequality of recent times.

Jennifer Burns is a professor at Stanford University, where she teaches 20th century American history. Her research focuses on how capitalism and the power of the market have influenced the American Political Economy. Burns' new book is Milton Friedman: The Last Conservative.
