Before Theodore Roosevelt gave it the name White House, it was known as the Executive Mansion.
Theodore Roosevelt was the first President to refer to the Executive Mansion as the White House.
The White house is also called the executive Mansion.
Executive mansion
Although originally called the President's Palace, the Presidential Mansion, or the President's House, the formal name was the Executive Mansion. References to the home as the White House appear as early as 1811. President Theodore Roosevelt made formal the usage in 1901 when he had the "White House" name added to the official stationery.
One other name for it is the Executive Mansion.
The White House's original official name was the Executive Mansion, though people generally referred to it as the President's House, the President's Palace, or the Presidential Mansion. It was first called the White House in 1811, and not, as is commonly thought, after the building was repaired and repainted after the War of 1812. The building was still officially called the Executive Mansion until Theodore Roosevelt, in 1901 and 1902, had the White House written on the official stationery and issued a proclamation establishing the new name.
The President's House and the Executive Mansion
It's somewhat surprising to learn the White House of the United States of America had been previously called the "President's Palace," the "President's House," and the "Executive Mansion." References to 'mansion' harkens back to the 1700s when most 'large houses' were called mansions and often had many hundreds of acres surrounding the home. In 1901, President Theodore Roosevelt officially gave "The White House" its current name.
It did not really have an official name, I think. People called it the executive mansion or the president's home. It was unofficially called the Whjte House for a long time before T. Roosevelt used that term on his official stationery.
No, the White House came later. The name, "White House" was the idea of President Teddy Roosevelt who wanted a more down-to-earth name than "Executive Mansion". There was an executive mansion in the first capital of the US: Philadelphia, though.
The president's mansion is called the White House. That name is unofficial; it is referred to as the executive mansion in Congressional directives.
