On this day 50 years ago, John Fitzgerald Kennedy became President of the United States.
In the morning, he attended Mass at Holy Trinity Church in Georgetown. He walked through the snow from his house at 3307 N Street. It was the Feast of Sts. Fabian and Sebastian, Martyrs.
A few hours later, President Kennedy delivered his Inaugural Address.
