The name Executive Mansion was used in official contexts until President Theodore Roosevelt established the formal name by having the de facto name White HouseâWashington engraved on the stationery in 1901.
In November 1800, John Adams became the first president to reside in the White House. Construction of the presidential home, which was designed by Irish-born architect James Hoban, began in 1792. President Theodore Roosevelt (1858-1919) officially named it the White House in 1901.
