Just been diving into the history of technical analysis, and you can't ignore William Delbert Gann. This guy's literally a legend in trading circles, and his influence on how we analyze markets today is still massive.

So here's the thing - Gann came from humble beginnings in Texas back in 1878. Started out with minimal formal education, but he was hungry to learn. Worked his way up from cotton warehouses to landing a job at a brokerage firm in Texarkana. By 1903, he decided to go all in and founded W.D. Gann & Company. That move basically launched what would become one of the most influential trading careers in financial history.

What really set William Delbert Gann apart was his approach to technical analysis. He developed these geometric-based methods - Gann Angles and Gann Fans - that tried to predict market movements using mathematical principles and pattern recognition. Pretty unconventional for his time, honestly. Some people thought his methods were eccentric, mixing geometry with market analysis in ways nobody else was doing.

Between the 1930s and 1940s, Gann put out several influential books. 'Wall Street Stock Selector' dropped in 1930, followed by works on commodities and options trading. These publications became go-to references for traders trying to understand technical analysis beyond just reading price charts.

Looking back, William Delbert Gann's legacy is undeniable. Whether you agree with all his methods or not, the guy fundamentally changed how people think about market analysis. His techniques are still studied and debated today, which tells you something about the depth of his contributions. 📈
