Daniel B. Zimmerman Mansion

The Daniel B. Zimmerman Mansion is a three-story brick building in Somerset Township with a five-bay center section and hipped roof designed by Philadelphia architect Horace Trumbauer. The structure features asymmetrical wings built in the Georgian Revival style typical of early 1900s wealthy estates.

The house was built in 1915 by Daniel B. Zimmerman, a businessman who made his fortune in coal mining and cattle shipping operations. The choice of hiring Horace Trumbauer, a prominent Philadelphia architect, reflected how wealthy industrialists brought major designers to build their estates.

The mansion shows how successful industrialists of the early 1900s liked to display their wealth and status through grand entertaining spaces and formal architecture. These homes were statements of power and accomplishment in the business world.

The property operates as a guest lodging and event venue, so visitors can often view the interior during tours or special occasions. Planning your visit around open events or tours gives you the best chance to experience the rooms and their original details.

The original owner started working at age 14 in cattle dealing and later created one of the earliest short-term automobile insurance companies. This unusual business shift shows how some early 1900s entrepreneurs found new markets in unexpected places.
