Charles Mackay 
Memoirs of Extraordinary Popular Delusions and the Madness of Crowds 

Extraordinary Popular Delusions and the Madness of Crowds is an early study of crowd psychology by Scottish journalist Charles Mackay, first published in 1841 under the title Memoirs of Extraordinary Popular Delusions. First published in 1841, Extraordinary Popular Delusions and the Madness of Crowds is often cited as the best book ever written about market psychology. This Harriman House edition includes Charles Mackay’s account of the three infamous financial manias — John Law’s Mississipi Scheme, the South Sea Bubble, and Tulipomania. The South Sea Bubble, Witch Mania, Alchemy, the Crusades, Fortune-telling, Haunted Houses, and even ‘Tulipomania’ are only some of the subjects covered in this book, which is given a contemporary perspective through Professor Norman Stone’s lively new Introduction.
