Dr. Hess Products were sold by Hoffman Coal

Dr. Hess products were claimed to help produce healthy flesh and milk in the animals consuming them, and hens were supposed to be more productive in laying eggs.  In the late 1800s and early 1900s, a local place to purchase Dr. Hess goods was  Daniel Hoffman, Dealer in Coal and Wood. The Hoffman family in Sandusky was in the coal business for over sixty five years, beginning in the late 1880s. The advertisement below was from December 5, 1896. At that time the business was on Scott Street, between Hancock Street and the B & O Railroad crossing. By 1897 the business was known as Daniel Hoffman, Dealer in Flour, Feed and Coal.

Some of the products with the Dr. Hess brand were Poultry Pan-A-Ce-A and Instant Louse Killer. 

In 1911 the name of the business changed again, to Hoffman Coal & Milling Co., Dealers in Flour, Feed, Seeds, Coal, Salt, Etc. At this time Dr. Hess had changed its logo to a colorful illustration with cattle and poultry, as seen at the top of this post.
