John Welles Wilder Jr. (June 11, 1935 – April 18, 2021) was an American mechanical engineer, turned real estate developer. He is best known, however, for his work in technical analysis. Wilder is the father of several technical indicators that are now considered to be the core tenets of technical analysis software. These include Average True Range, the Relative Strength Index (RSI), Average Directional Index, and the Parabolic SAR.[1]
