In 1883, during the transition from rugby and Canadian football to Americanized football, Walter Camp authored new point values. A touchdown became 4 points, the extra (point) kick became 2 pts, a field goal became 5 pts. and a safety 2 pts. In 1910 the Intercollegic football assoc. adopted the current point schedule that we use today, 6pt for a TD, etc. They also changed the dimentions of the field to its current size and added a fourth down to play.
