Outlining briefly the people and discoveries relating to economic cycles. Beginning with Sir William Herschel who around 1800 found a connection between the Sunspot cycle and wheat prices, mention is made of Clement Juglar 1860s, William Stanley Jevons 1870s, The Rothschild family 1890s and Rockerfeller family, W D Gann 1900s, Joseph Kitchin 1920, Kondratief (who I accidentally left out of this video) and his 54 year cycle in the 1920s, Alexander Chizhevsky and Raymond Wheeler around the 1930s being interisciplinary cycles researchers, R N Elliott, Joseph Schumpeter and Simon Kuznets (later to receive a Nobel Prize) and the formation of the Foundation for the Study of Cycles by Edward R Dewey and others in 1942. The age of computers arrived in cycles research with J M Hurst about 1970.
