After Hermon Hosmer Scott worked for the General Radio Company, in Cambridge, MA from 1931 to 1946, serving first as Sales Engineer/Development Engineer and later as Executive Engineer in charge of Audio, Acoustic, Broadcast and related developments, he founded the Technology Instrument Corporation, of Waltham, MA in 1946. I.T.C.'s first product was the Type 910-A; a 13-tube, 19-inch, rack-mounted, Dynamic Noise Suppressor marketed to commercial broadcasters and permitted stations to greatly reduce their dependence on live performances.

In 1947 Scott founded his H.H. Scott, with a rustic old shoe factory as place in Cambridge, MA. It has then built the first integrated Hi-Fi phon amplifier 210-A. In 1957 the company moved into a new atate-of-the-art manufacturing and research facility at Powder Mill Road in Maynard, MA.

The company remained independent until 1973, when it was acquired by Electro Audio Dynamics of Europe. US operations were later relocated to Woburn, MA, offices. In 1985, the famous hi-fi brand was purchased and today operates as a division of Emerson Electronics.
