Including this year, the Open Championship has been cancelled 13 times. The first was in 1871, when no trophy was available because Tom Morris Jr. had retired the famed Challenge Belt – made of red Moroccan leather and considered today golf’s most prized piece of memorabilia. Under Open rules, the belt was Morris’s property having won three consecutive titles. The claret jug was introduced in 1872, when Young Tom won again. From 1915-19, the Open was cancelled because of World War I; and from 1940-45, due to World War II.
PGA of America Charter Member Walter Hagen and PGA Member Jim Barnes – both survivors of the “Spanish Flu” pandemic in 1918, became the first major champions following World War I.
