Examples of Marblehead Pottery bearing impressed or painted 'HT' cyphers have previously been attributed to the enigmatic figure of Hannah Lucy Tutt (1860-1952), a bookkeeper and Marblehead native who appears to have had no direct connection to the pottery's production. An article written by Jonathan Clancy and Martin Eidelberg and published in November 2008 by Style 1900 presents a deep study of the cypher and dispels the Hannah Tutt attribution, establishing that Marblehead's artists' marks combine an initial from each piece's designer and executor, with 'HT' corresponding to the designer Arthur Irwin Hennessey (1882-1923) and the potter and decorator Sarah Tutt (1859-1947). Clancy and Eidelberg support their thesis by comparing extant marks to designer identifications provided by a 1908 article on Marblehead in Keramic Studio, which also records 'Mr. A.I. Hennessey' as a designer and 'Mrs. E.D. Tutt' (Sarah, identified by the initials of her husband, Edward D. Tutt) as 'the decorator.' See J. Clancy and M. Eidelberg, “Marblehead Revisited: The Myth of Hannah Tutt,” Style 1900, November 2008, and H.J. Hall, 'Marblehead Pottery,' Keramic Studio 10, June 1908, pp. 30-31.
