19th Century Scottish Chemist: The most likely candidate you're interested in is the 19th-century Scottish chemist Thomas Anderson. He lived from 1819 to 1874 and made significant contributions to our understanding of alkaloids, discovering the correct formula for codeine in 1853. His most famous discovery though, was pyridine, which he isolated from bone oil in 1868. While he likely published research papers, he wouldn't be known as an author in the traditional sense.
