The Wallace & Company was formed on January 20, 1912.

Wallace & Co.; New York City, New York, was formed by Paul E. Wallace and his assistant Merritt D. Mosher. Wallace had moved to New York in February 1911 and had rented space from the O. T. Louis Company and went into business as the "O.T. Louis Wireless Department". In the summer of 1911 Wallace had introduced the Wallace Valve Detector using the Audion tube, which Lee deForest would directly copy and introduce as the RJ4 in November 1913. Wallace had also introduced his Wallace Valve Receiver in the summer of 1911. This receiver utilized a regenerative circuit two years before it was "invented" by E.H. Armstrong. It is interesting to note that Armstrong was one of the many visitors to the Wallace workshop and as a college sophomore had operated the Wallace Receiver on several occasions.
