Jack Lalanne

Francois Henri "Jack" LaLanne (26 September 191423 January 2011) was an American fitness, exercise, and nutritional expert and motivational speaker who is sometimes called "the godfather of fitness" and the "first fitness superhero." He described himself as being a "sugarholic" and a "junk food junkie" until he was 15. He also had behavioral problems, but "turned his life around" after listening to a public lecture about the benefits of good nutrition. During his career, he came to believe that the country's overall health depended on the health of its population, writing that "physical culture and nutrition — is the salvation of America."
