William Delbert Gann was born on June 6, 1878, near Lufkin, Texas. He was the eldest of a large family and grew up working on his family's farm. He left school at an early age and began working while still young.

As a teenager, Gann worked as a cigar and newspaper vendor on the railway. There he listened to conversations about cotton, commodities and business, which sparked his interest in the markets. He later worked for a brokerage firm in Texarkana, Texas, while attending business school at night.

Gann eventually moved to New York and continued his study of the financial markets. He became particularly interested in the relationship between time and price and in the possibility of identifying recurring patterns in market behaviour.

In his later writings, Gann described August 8, 1908, as the date of one of his most important mathematical discoveries relating to the prediction of market trends. He also reported substantial trading results from this period, including turning a $300 account into $25,000 and a $130 account into $12,000 in thirty days.

In 1909, Gann's work attracted public attention. The Ticker and Investment Digest published an article about his trading record, including an account of his famous September wheat prediction. According to the article, Gann had predicted that September wheat would reach $1.20 before the end of the month. On the final trading day, the price reached $1.20 during the last hour of trading.

This account became one of the best-known stories associated with Gann's early trading career.

Gann continued to develop and publish his ideas throughout his life. His work explored the relationship between time, price, cycles, geometry and other subjects that he believed could help explain market behaviour.

In 1923, he published Truth of the Stock Tape, followed by other works including Wall Street Stock Selector and The Tunnel Thru the Air.  Gann also became known for a number of long-range predictions concerning financial markets and major world events. Some of these predictions are documented in contemporary publications and in Gann's own writings, while others have been debated and interpreted differently by later researchers.

Among the material associated with Gann are records of his reported trading results during the 1930s. These figures have contributed to his reputation as one of the more unusual and controversial figures in the history of market analysis.

Gann continued studying and writing about the markets for the remainder of his life. His work has since become the foundation for a broad body of research into time cycles, price movements, geometric relationships and market forecasting.
