Oliver B. Shallenberger
Oliver Blackburn Shallenberger (May 7, 1860 – January 23, 1898) was an American engineer and inventor.
In 1877 he entered the United States Naval Academy at Annapolis. After his graduation he spent two years on the U. S. flag-ship Lancaster in the Mediterranean, resigning in 1884. The Union Switch and Signal Company, of Pittsburgh, under the management of George Westinghouse, was at that time organizing an electric light department, and Mr. Shallenberger became associated with that work.
On November 27, 1889 he married Mary Woolslair. They had a son and daughter. In 1891, poor health required him to resign from the Westinghouse company but he continued as a consultant. In 1897 he had organized the Colorado Electric Power Company.
