Thaddeus Cahill (June 18, 1867 – April 12, 1934) was a prominent american inventor of the early 20th century. He is widely credited with the invention of the first electromechanical musical instrument, which he dubbed the telharmonium.
The invention was unveiled to the public in April 1935, and the first model, the Model A, was made available in June of that year. [4] Over 1,750 churches purchased a Hammond organ in the first three years of production, and by the end of the 1930s, over 200 instruments were being made each month. [ 40 ]
