Macmillan Publishers USA was the former name of a now mostly defunct American publishing company. Once the American division of the British Macmillan Publishers, remnants of the original American Macmillan are present in McGraw-Hill Education's Macmillan/McGraw-Hill textbooks and Gale's Macmillan Reference USA division. The German publisher Holtzbrinck, which bought Macmillan UK in 1999, purchased most US rights to the name in 2001 and rebranded its American division with it in 2007.
George Edward Brett opened the first Macmillan office in the United States in 1869 and Macmillan sold its U.S. operations to the Brett family, George Platt Brett, Sr. and George Platt Brett Jr. in 1896, resulting in the creation of an American company, Macmillan Publishing. Even with the split of the American company from its parent company in Britain, George Brett Jr. and Harold Macmillan remained close personal friends.
George P. Brett Jr. made the following comments in a letter dated 23 January 1947 to Daniel Macmillan about his family's devotion to the American publishing industry:
That sinking feeling when you’re not yourself:
searching for a reason for some kind of help,
but all that comes is empty promises and feeling anxious and useless.
Then, when I’m my worst, comes someone who I don’t deserve.
I’ll call her destroyer, and I’ll destroy her.
