Archimedes was one of three horses named by Emmett Brown in 1885, along with Galileo and Newton. He was named after the mathematician Archimedes. Archimedes and Galileo had stalls in Emmett's blacksmith shop between the door and Doc's refrigerator, with their names written on signs above the entrances to their stalls. He was the horse that Doc rode to chase after the train on September 7.[1]
