Biographical/Historical Note

Thaddeus Mason Harris (1768-1842) was a native of Massachusetts. A graduate of Harvard, he worked in Harvard’s library from 1791-1793. He then became a Unitarian clergyman. In December 1833, he spent five months in Georgia compiling information for his Biographical Memorials of James Oglethorpe, which was published in 1841. Harris resigned his pastorate in 1836, and from 1837 until his death, he was the librarian of the Massachusetts Historical Society. His son, Thaddeus William Harris (1795-1856), was also librarian at Harvard.

Scope and Content Note

This collection contains manuscripts and materials relating to Thaddeus Mason Harris’ 1841 book, Biographical Memorials of James Oglethorpe. There are research materials, illustrations for the book, letters to Harris about the book, receipts, copyright documents, information about the Salzburgers, and a lecture on General Oglethorpe by Joseph Willard. There are also two copies of Harris’ Biographical Memorials of James Oglethorpe. One copy is pasted inside a scrapbook and appears to be a draft, as it has editing marks on it. The second copy is the published version.

The miscellaneous file in this collection contains a list of “family treasures” and an obituary for Harris’ grandson, Charles Harris, who died in Cambridge, Massachusetts around 1908. The dated materials in this collection are from 1841, but the research materials are probably from the 1830s.
