On November 27, 1963, Charles Jack Price, administrator of Parkland Memorial Hospital in Dallas, wrote:
At 12:38 p.m., Friday, November 22, 1963, President John F. Kennedy and Texas' Governor John Connally were brought to the Emergency Room of Parkland Memorial Hospital after being struck down by the bullets of an assassin. . . .
In the intervening 48 hours and 31 minutes Parkland Memorial Hospital had:
1. Become the temporary seat of the government of the United States.
2. Become the temporary seat of the government of the State of Texas.
