Tristram Risdon (c. 1580 – 1640) was an English antiquarian and topographer, and the author of Survey of the County of Devon. He was able to devote most of his life to writing this work. After he completed it in about 1632 it circulated around interested people in several manuscript copies for almost 80 years before it was first published by Edmund Curll in a very inferior form. A full version was not published until 1811. Risdon also collected information about genealogy and heraldry in a note-book; this was edited and published in 1897.
