Luther James Jensen, perhaps better known as “L.J. Jensen,” wrote Astro-Cycles & Speculative Markets. This book jacket for this book describes it as “a major contribution in the field of economic forecasting…this allows you to pinpoint weeks in advance the Longitude and Latitude where a trend will be centered, and how it will affect business, weather or a natural disaster.”
In 1931 Jensen opened the “Kansas City Bureau of Economic Research,” which was speculated to have a very wealthy, yet unknown client. Soon after W.D. Gann died in 1955, the Kansas Bureau of Economic Research closed its doors. Jensen then worked for B.C. Christopher and Co. of New York from 1957 until his retirement in 1971.
