W.D.Gann – Master Calculator for Time Periods, 1955
William Delbert Gann (June 6, 1878 – June 18, 1955) or WD Gann, was a finance trader who developed the technical analysis tools known as Gann angles, Square of 9, Hexagon, Circle of 360 (these are Master charts). Gann market forecasting methods are based on geometry, astronomy and astrology, and ancient mathematics. Opinions are sharply divided on the value and relevance of his work. Gann wrote a number of books on trading.
Gann was born June 6, 1878 in Lufkin, Texas. His father was a cotton farmer. He started trading in 1902 when he was 24.
He was believed to be a religious man by nature who believed in religious as well as scientific value of Bible as the greatest book ever written. This can be repeatedly observed in his books. He was also a 33rd degree Freemason of the Scottish Rite Order, to which some have attributed his knowledge of ancient mathematics, though he was also known to have studied the ancient Greek and Egyptian cultures.
