Kehr Bros.

est. 1906


A century ago, Frank and Emil Kehr opened the door of Kehr Bros., at 111 S. 5th Street in Watertown [currently located at W4631 Hwy 19].  They began taking orders for steamfitting, boiler and gas piping projects using a pad of paper and pencil. Customers at that time who had telephones could call in for service by dialing 168.


Following the death of Emil in 1936 his son Donald E. Kehr became a partner with Frank Kehr and they started selling and installing gravity furnaces and oil fired forced air furnaces.


Following the death of Frank Kehr in 1951 his son Robert T. Kehr became a partner with Donald E. Kehr.  At that time they began selling and installing refrigerated air conditioners.


Upon Donald E. Kehr's retirement in 1969, Robert T. Kehr then purchased his share of the business.



Kehr Bros awarded the contract for installing a heating system in the building being erected on Second Street by Gustave [Gustav] Neumann.
