Brand: John Thoreau & Co.
Made in: USA
This particular pencil comes to me by way of a large Victorian in West Roxbury, Massachusetts. Mounted as such and who knows for how long. The pencil is circa 1830's.
According to the Concord Museum there are three known printings on the pencils: J. Thoreau & Son Concord Mass"; one is stamped "John Thoreau" and one is stamped "J Thoreau & Co.", as seen above.
Based in Concord, Massachusetts and manufactured pencils between about 1824 and 1852. Henery David would have been around seven years old when his father started the company. Apparently, after graduating Harvard in 1838 and possibly even during his Harvard years, Henery worked with his father in the family pencil business. They eventually elevated the quality of the lead to a highly prized status.
