Henry Hamilton Bailey (1 October 1894 – 25 March 1961) was a British surgeon. Bailey became one of the most influential authors of surgical textbooks in the 20th century; when publishing, and perhaps for much of his working life, he dropped his first name, becoming Hamilton Bailey. He was a pioneer in the use of illustrations and photographs in surgical textbooks. **Source**: [Hamilton Bailey](https://en.wikipedia.org/wiki/Henry_Hamilton_Bailey) on Wikipedia
