Established in 1922 Dukane is a diversified global manufacturer of advanced technology products. A privately held corporation for more than 95 years, Dukane's principal manufacturing and distribution facility is located in the Chicago western suburb of St. Charles, Illinois.
J. Mc William Stone, Sr., „Mac“, founded the company in September, 1922. Stone chose the name „Operadio“ for it connotations of quality music and fine tone. Upon discovering that the Chicago music firm Lyon and Healy had registered the trademark „Radiopera“ the month before, Stone bought it from them to avoid conflict. Lyon and Healy became a distributor.
Operadio displays at World Fair Chicago and builds a talking robot for Sear’s Roebuck.
The first Audio-Visual product designed, sold 5,500 units. It was a „talking“ filmstrip projector used for sales training and as a sales tool.

Dukane opened Ionavac® Division and enters the High Fidelity Stereo Speaker Market. The technology is based on Dukane’s Patented Inertialess Transducer which produces amazingly clear high frequency response. The IONOVAC® offered an entirely new concept of sound reproduction. It was new and different because an ionic cloud replaced the diaphragm used in ordinary speakers. Sound was generated and transmitted inside a tiny quartz cell no larger than a dime.
NASA requests Dukane to assist them in writing the specs for a similar underwater locating device for use on commercial aircraft with flight data recorders in anticipation of Federal Regulations (FAA). Dukane then developed and produced the product for sale to major commercial airlines.
