On November 13, 1875, Yale and Harvard played each other for the first time ever, where Harvard won 4–0. At the first The Game—the annual contest between Harvard and Yale, among the 2000 spectators attending the game that day, was the future "father of American football" Walter Camp. Walter, who would enroll at Yale the next year, was torn between an admiration for Harvard's style of play and the misery of the Yale defeat and became determined to avenge Yale's defeat. Spectators from Princeton admired this type of game and it became the most popular version of football there. Walter Camp: Father of American football Walter Camp is widely considered to be the most important figure in the development of American football. As a youth, he excelled in sports like track, baseball, and association football, and after enrolling at Yale in 1876, he earned varsity honors in every sport the school offered. Following the introduction of rugby-style rules to American football, Camp became a fixture at the Massasoit House conventions where rules were debated and changed. Dissatisfied with what seemed to him to be a disorganized mob, he proposed his first rule change at the first meeting he attended in 1878: a reduction from fifteen players to eleven. The motion was rejected at that time but passed in 1880. The effect was to open up the game and emphasize speed over strength. Camp's most famous change, the establishment of the line of scrimmage and the snap from center to quarterback, was also passed in 1880. Originally, the snap was executed with the foot of the center. Later changes made it possible to snap the ball with the hands, either through the air or by a direct hand-to-hand pass. Camp's new scrimmage rules revolutionized the game, though not always as intended. Princeton, in particular, used scrimmage play to slow the game, making incremental progress towards the end zone during each down. Rather than increase scoring, which had been Camp's original intent, the rule was exploited to maintain control of the ball for the entire game, resulting in slow, unexciting contests. At the 1882 rules meeting, Camp proposed that a team be required to advance the ball a minimum of five yards within three downs. These down-and-distance rules, combined with the establishment of the line of scrimmage and forward pass, transformed the game from a variation of rugby football into the distinct
