On Thanksgiving Day—100 years ago—many of the Grinnell students who remained on campus gathered in the auditorium of A.R.H to “watch” their football team play the last game of the season against their rival, Creighton, in Omaha. The college marching band assembled in the auditorium, along with Grinnell’s cheerleading squad, but all eyes were on the new “Grid-Graph” machine, which weighed nearly 1,000 pounds, and was designed to visualize remote football matches via instant telegraphy, electrical switches, and lights, so that fans could follow the action in real time, play-by-play (in an era before television coverage, and when even radio broadcasting of games was limited to a few nationally chosen matches). In the 1920s, Grid-Graph became all the rage in college sports, and Grinnell was excited to sign its own contract in 1924 to bring the marvels of modern technology (the “electric gridiron”) to campus.
