What is a Daguerreotype Composition Factory? One can only speculate that based on Anderson’s occupations that it has something to do with manufacturing pigments for coloring daguerreotypes.
The original information about the Daguerreotype Composition Factory was brought to my attention by Ronald J. and Mary S. Zboray while they were doing research at the Massachusetts Historical Society. William T. Anderson is not included in A Directory of Massachusetts Photographers, 1839-1900.
