The Alexander Metcalf Fisher papers consist of correspondence, scientific and personal writings, school notes, eulogies, and other material by or about the Yale College student (Class of 1813) and Yale professor. Drafts and calculations for articles on mathematics, physics, astronomy, and other subjects published between 1817 and 1822, as well as scripts for forty lectures in natural philosophy, illustrate Fisher's academic career in the context of contemporary scientific learning. Documenting the social, economic, religious, and emotional life of a young man living in New England during the Early Republic are extensive correspondence written by Fisher to his parents from 1809-1821, and eight personal and travel diaries. Correspondents also include other relatives, the Fisher family's pastor Nathanael Emmons, and Yale affiliates. Also contained in the collection is a portrait of Fisher engraved on copper by Simeon Smith Jocelyn.
