Fabian Stedman (1640–1713) was an English author and a leading figure in the early history of campanology, particularly in the field of method ringing. He had a key role in publishing two books Tintinnalogia (1668 with Richard Duckworth) and Campanalogia (1677 – written solely by him) which are the first two publications on the subject. He is also regarded as being a pioneer in the branch of mathematics known as Group theory.
