Hours after the Inauguration, Roosevelt made history in a more behind-the-scenes way. He gathered his Cabinet in his White House office and had Justice Benjamin Cardozo swear them in as a group, the first time that had ever been done. F.D.R. joked that he was doing it so they could "receive an extra day's pay," but the real reason was that he wanted his team to get to work immediately.
And that team came through brilliantly. In the next 100 days — O.K., 105, but who's counting? — his Administration shepherded 15 major bills through Congress. (Time, 2016)
