He was one of the most prominent and most celebrated economists in America during the early part of the twentieth century. He is credited with pioneering many of the principles that are the foundation of central bank policy. Fisher was financially wiped out during the Great Depression. He also invented the Rolodex. In 1927 Clarence Darrow and Victor S. Yarros wrote a book titled "The Prohibition Mania: a Reply to Professor Irving Fisher and Others."
