American commerce and invention suffered a terrible blow on December 15, 1836, when the U.S. Patent Office caught fire. The office, which was located in Blodget’s Hotel on E Street NW between 7th and 8th Streets, shared its space with the U.S. Post Office and a branch of the local fire department, of all things. Unfortunately, that volunteer fire department had disbanded and the only way to fight the flames was a bucket brigade. When the fire was finally doused, America lost an estimated 7,000 models and 9,000 drawings of pending and patented inventions.
