The switch to the T Formation was 1949, jimv. As for the other date, Columbia ended Army's 32 game winning streak in October 1947. I was at that game with my mom who was a huge fan of Lou Little's Lions, and the reason Columbia later became my alma mater. What she didn't know at the time was that I was rooting for Army. In any case, it wasn't Pitchin' Paul Governali but Gene Rossides who threw the famous pass to Bill Swiaki who caught it with his finger tips to cut the score to 20-14. He made another 4th Quarter catch on the Army 3 yard line after which Lou Kusserow ran it in to make the final score 21-20. Rossides and Kusserow were known as the Gold Dust Twins.
