Did any famous authors ever publish their own books?
The late Oral Roberts did. He had the marketing ability to sell his books -- and little need for a publisher.

Scott Adams, creator of the Dilbert comic strip and book series self-published an original e-book, God's Debris, in 2001 as a way of testing the market for that book. As a result, he was able to get what he called an “unusually good deal” from his publisher when he sold the rights.

What Color is Your Parachute was self-published by Episcopal clergymen Richard Nelson Bolles. Ten Speed Press saw it and made him an offer. It has now sold 5 million copies and spent 288 weeks on the New York Times bestseller list.

In 1998, Arthur Agatston, author of The South Beach Diet, began by self-publishing several hundred pamphlets outlining his diet ideas for patients. Several years later, he sold the rights to Rodale Press, publishers of Prevention. Within a year, the book had sold almost seven million copies.

Edgar Allen Poe didn't trust publishers and printed up his own books. First editions today are enormously valuable.

Beatrix Potter sat down to write a picture letter to a five-year old friend. She really didn't know what to write to the child so she penned him a story about four little rabbits. The Tale of Peter Rabbit was rejected by numerous publishers, so she self-published 250 copies. Publisher Frederick Warne, who had rejected the book, changed his mind when he saw the finished product. One hundred years later, it is still selling well.

John Bartlett financed the publication of the first three editions of his famous book of quotations.
