Who gave The White House its current official name in 1901 and what names were used before that?

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.
