You can say that Thomas Peebles and Johnny Campbell were both responsible for the introduction of cheerleading:
Princeton graduate Thomas Peebles introduced the idea of organized crowds cheering at football games to the University of Minnesota. However, it was not until 1898 that University of Minnesota student Johnny Campbell directed a crowd in cheering "Rah, Rah, Rah! Sku-u-mar, Hoo-Rah! Hoo-Rah! Varsity! Varsity! Varsity, Minn-e-So-Tah!”, making Campbell the very first cheerleader and November 2, 1898 the official birth date of organized cheerleading.
