Harvard and Princeton have a rich football rivarly dating back to 1877 when they first met at Cambridge. The first meeting was a historic game as it was the first time that canvas jackets were worn. Formerly games had been frequently interrupted because jerseys and clothing would be torn off the players, for a runner could only be tackled above the hips. In March, 1877, L.B. Smock (Harvard ’79) made a canvas jacket which he wore to a Harvard game. Later these jackets were work by all colleges.
The games in 1877, 1878 and 1879 were held on the St. George’s Cricket Grounds in Hoboken, NJ. The games in 1880 and 1881 were played on the Polo Grounds in New York City. Subsequent games were played at either Harvard or Princeton.
All these fascinating and historical facts were taken from the Princeton v. Harvard football program from 1961 which featured a special historical section on Princeton v. Harvard games.
