Hackstaff Brothers Inc.

A Denver, Colorado Company for 75 Years
Originally located at:
875 Navajo Street
Denver, Colorado 80204
Phone: KEystone 3558 and later 266-0351

   In June 1947, Addison Hackstaff purchased Denver Fuel Supply from Harold C. Rutter. The corporation was formally formed on June 18th. Addison was the President, Howard Hackstaff was the Treasurer and Julia (Hackstaff) Calloway was the Secretary.

   In 1950, the company name was changed to Hackstaff Brothers Incorporated. Also in 1950, the company purchased a transport truck to get the fuel from Fontier Oil in Wyoming to Denver. Up to this time, Frontier Oil had been very unreliable in meeting the company gas delivery needs.

   In 1956 the company had had enough with trying to work with Frontier Oil and switched to Standard Oil. Also in this year, a 26 year old Dale Hackstaff (son of Addison and father of Eddie, me...) joined the company.

   In 1970 the fuel and parts supply portion of the business was liquidated and the property ownership and leasing continued.
