Contract between William Beaumont and Alexis St. Martin, October 1832
As he was finalizing his research for publication, Beaumont had Alexis St. Martin submit to a legal contract binding him for one year to “obey, suffer & comply with all reasonable & proper orders or experiments,” in return for $150 plus “good, suitable & sufficient meat, drink, washing, lodging and wearing apparel.” St. Martin, unable to write his own name, signed the document with an “x.”
