Thinking outside the coffin
Irving Fisher (1867-1947) was a neoclassical economist. I say “was” not merely because he is dead, but also because he emphatically rejected the neoclassical approach after his “Near Death Experience” during the Great Depression.
Fisher was worth over $US100 million in today’s money when The Great Crash began. Unlike most economists, he was also an inventor, and he invented a predecessor of the Rolodex – the iPad of its day. He sold his invention to the predecessor of Unisys in return for shares and a seat on the board – and like so many others back then, levered his wealth by buying shares on margin.
