Robert Eugene Ladouceur (born July 3, 1954) is a retired American football coach. He began coaching the De La Salle High Spartans in Concord, California in 1979 when he was 25 years old. He took over a program that never had a winning season since the school's establishment in 1965. His first season as head coach resulted in their first winning season. His second season resulted in their first appearance in the California Prep Football State Rankings and began De La Salle's evolution into a perennial champion. From 1992 to 2004, he guided the team to 12 consecutive undefeated seasons, setting a national winning streak record for high school football of 151 consecutive wins—a record in US amateur sports exceeded only by the 159-game winning streak of Passaic High School in men's basketball and the 459 match win streak of Brandon High School in men's wrestling.^[1] Ladouceur was enshrined to the National High School Hall of Fame in 2001. His team topped the USA Today rankings five times and he is a three-time coach of the year. He retired on January 4, 2013 with a career record of 399–25–3.^[2] His .934 winning percentage is a record among coaches with 200 or more wins. Ladouceur is the all-time winningest coach in California high school football and has led the De La Salle program to numerous championships. A film about his life called When the Game Stands Tall was released on August 22, 2014. The film, which stars Jim Caviezel as Coach Bob Ladouceur, Laura Dern as Bev Ladouceur, Michael Chiklis as assistant coach Terry Eidson, and Alexander Ludwig as running back Chris Ryan, is about the record-setting 151-game 1992–2003 high school football winning streak by De La Salle High School of Concord, California. The film is an adaptation of the 2003 book of the same name by Neil Hayes and published by North Atlantic Books. Bob married Lissa Ladouceur on January 3, 2015. De La Salle head coach Bob Ladouceur retired in January 2013 after winning his last Open Division state championship in December 2012.
