Harvard Mark I Operating

Harvard University President James Conant writes to IBM founder Thomas Watson Sr. to let him know that the Harvard Mark I, developed in cooperation between the two, was operating smoothly. The project was one of the many examples of wartime collaboration among the federal government, universities, and private corporations. In his letter, Conant noted that the Mark I already was "being used for special problems in connection with the war effort."
