Macmillan Publishers (occasionally known as the Macmillan Group; formally Macmillan Publishers Ltd in the UK and Macmillan Publishing Group, LLC in the US) is a British publishing company traditionally considered to be one of the "Big Five" English language publishers (along with Penguin Random House, Hachette, HarperCollins and Simon & Schuster). Founded in London in 1843 by Scottish brothers Daniel and Alexander MacMillan, the firm would soon establish itself as a leading publisher in Britain. It published two of the best-known works of Victorian-era children's literature, Lewis Carroll's Alice's Adventures in Wonderland (1865) and Rudyard Kipling's The Jungle Book (1894).[4][5] Former Prime Minister of the United Kingdom, Harold Macmillan, grandson of co-founder Daniel, was chairman of the company from 1964 until his death in December 1986. Since 1999, Macmillan has been a wholly owned subsidiary of Holtzbrinck Publishing Group with offices in 41 countries worldwide and operations in more than thirty others.
