This is the cover of (unfortunately) the final edition of The Worldly Philosophers by Robert L. Heilbroner. This book introduces economic ideas through the lives of great economists.
The eccentricities (and bad French) of Adam Smith. The carbuncles and chaotic lifestyle of Karl Marx. The wanderlust and lasting impact of Henry George. The infidelity and genius of Thorstein Veblen. The heresies and fortune of John Maynard Keynes.
This book does not replace a “real” course (or book) on economics, but it is a wonderful introduction; it also provides insights into why some of these economic theories developed.
