In November 1919 and January 1920, in what notoriously became known as the âPalmer Raids,â Attorney General Mitchell Palmer began rounding up and deporting so-called radicals. Thousands of people were arrested without warrants and without regard to constitutional protections against unlawful search and seizure.
Palmer's most prolific years were 1960â1963, when he won 29 PGA Tour events, including five major tournament victories, in four seasons. In 1960, he won the Hickok Belt as the top professional athlete of the year and Sports Illustrated magazine's Sportsman of the Year award.
