Which U.S. president officially gave the White House its name?
President Theodore Roosevelt is the leader who officially bestowed the name “White House” upon the iconic presidential residence in 1901. Before this formal change, the building was commonly known by several different titles, including the President’s House, the President’s Palace, and most frequently in official documents, the Executive Mansion. Roosevelt, who was known for his decisive and energetic leadership style, felt that the existing names were either too royal or too generic, especially since many state governors also resided in structures referred to as executive mansions.
