International Radio Corporation

International Radio Corporation (IRC) was an American radio-receiver manufacturer established in 1931 in Ann Arbor, Michigan. The company was founded by Charles Albert Verschoor, an inventor and entrepreneur with earlier experience in radio and automobile manufacturing. Its creation was supported by approximately $10,000 raised by Ann Arbor mayor William E. Brown, Jr., and local business leaders who hoped to establish a growth-oriented company and create employment during the Great Depression. IRC operated from a former furniture factory at 405 Fourth Street on Ann Arbor’s west side. IRC’s early success came from combining relatively compact designs, low manufacturing costs, and new cabinet and circuit technologies. Its first receiver, the International Duo, was introduced in August 1931 and was designed to receive both local longwave broadcasts and European shortwave signals. The company soon introduced the Kadette, a small four-tube receiver that became one of its defining products. The Kadette was widely described as the first mass-produced AC/DC radio. By operating from either alternating or direct current, it could avoid the need for a power transformer, making it lighter, smaller, and less expensive than many competing sets. Its Bakelite plastic cabinet, produced by Chicago Molded Products Company, also helped IRC reduce costs and establish a distinctive product format. A customer kit allowed some Kadette sets to be adapted for battery operation in mobile settings, including automobiles and railroad cars. The Kadette’s popularity made IRC profitable relatively quickly. By 1933, it was reported to be the only Ann Arbor company still paying dividends to shareholders. IRC expanded the Kadette family with products such as the Kadette Jr., identified as an early pocket radio; the Kadette Jewel, offered in several color combinations; the Kadette Classic, which used multiple plastic treatments; and the Kadette Clockette, a clock-like receiver offered in several wooden case styles. The company also sold accessories, including the Tunemaster remote-control device and the Kadette Autime, described as the first mass-produced clock radio. IRC’s growth was eventually undermined by product and distribution problems. In 1937, the company introduced a low-priced ten-tube Kadette. Although its price was substantially below that of many competing ten-tube radios, reviewers criticized the design because several of its tubes were ballast tubes rather than active receiving tubes. Dealers also objected to the product’s low margins and to IRC’s requirement that they stock slower-selling models in order to obtain the more attractive ten-tube units. Discounting and declining dealer profitability weakened the Kadette line’s distribution and damaged relationships with retailers. Because radio sales were strongly seasonal, IRC sought a product that could generate demand during the summer. This diversification effort led Verschoor to develop an inexpensive, Leica-inspired camera. Introduced in 1936, the camera became the Argus and achieved rapid success, helping shift the company’s long-term prospects toward photography and optical equipment. That year IRC also sold its Kadette AC/DC patents to RCA. Verschoor left IRC in 1938 after pressure to depart, and the business was subsequently managed by a newer management team. In 1939, International Industries sold IRC’s radio-manufacturing operations to W. Keene Jackson, the company’s former general sales manager. Jackson renamed the operation Kadette Radio Corporation and announced ambitions to expand into television receivers, but the successor company lasted only about a year. IRC’s radio business therefore disappeared while the camera and optical activities associated with Argus continued to develop. During and after World War II, International Industries and its International Research division became wholly owned subsidiaries of Argus, Inc. The International name subsequently ceased to exist as…

International Radio Corporation emerged in Ann Arbor, Michigan, during the economic hardship of the Great Depression. Charles Albert Verschoor, who had worked in radio and automobile manufacturing, organized the company in 1931 with financial backing from Ann Arbor mayor William E. Brown, Jr., and local business leaders. Their investment was intended not only to support a promising manufacturer but also to create a local source of employment and industrial growth. IRC occupied a former furniture factory on Fourth Street. The company’s first receiver, the International Duo, appeared on August 7, 1931. Its ability to receive both local longwave broadcasts and European shortwave signals distinguished it from many contemporary table radios, while its relatively compact dimensions reflected IRC’s emphasis on accessible consumer products. The more important early product was the Kadette, a four-tube receiver that became an early mass-produced AC/DC radio. Its transformerless electrical design allowed operation from either alternating or direct current and reduced size, weight, and cost. The receiver’s Bakelite cabinet, manufactured by Chicago Molded Products Company, was also significant because plastic construction was less expensive than many traditional cabinet approaches. IRC promoted the Kadette as a portable product, and a modification kit enabled battery operation in mobile environments. The Kadette generated rapid commercial success. By 1933, IRC was reportedly the only Ann Arbor company still paying dividends, despite the difficult economic environment. The company developed a broad family of Kadette products, including the Kadette Jr. pocket radio, the multicolor Kadette Jewel, the plastic-bodied Kadette Classic, and the clock-like Kadette Clockette. IRC also produced accessories such as the Tunemaster remote control and the Kadette Autime clock radio. These products extended the brand beyond conventional table radios and reinforced its reputation for small, inexpensive, and technically distinctive receivers. IRC later encountered problems in product strategy and retail distribution. Radio demand was seasonal, with stronger sales during winter months. To use its manufacturing capabilities during the summer and reduce this seasonal exposure, Verschoor searched for a low-cost product suitable for warm-weather demand. He developed a Leica-inspired camera that became the Argus. Introduced in 1936, the camera was an immediate success and ultimately became more important to the company’s corporate future than the radio business. In the same year, IRC sold its Kadette AC/DC patents to RCA. The company’s radio strategy weakened in the late 1930s. A ten-tube Kadette introduced in 1937 was priced aggressively, but reviewers criticized it for using several ballast tubes that added to the advertised tube count without providing equivalent receiving performance. Dealers also found the model unattractive financially: margins were lower than those available on premium competitors, and IRC’s stocking requirements forced retailers to carry slower-moving products. Unauthorized discounting followed, reducing overall dealer returns and causing some retailers to remove Kadette products from their catalogs. Verschoor left IRC in 1938 after being pressured to depart. By the early 1940s, the company was being operated by a newer management team. In 1939, International Industries sold the radio operation to W. Keene Jackson, IRC’s former general sales manager. Jackson formed Kadette Radio Corporation and discussed adding television sets, but the successor lasted only about a year. This ended the direct radio-manufacturing continuity of IRC. The camera and optical businesses had a different trajectory. Argus sales grew, and the company expanded its workforce during World War II to support wartime production. After the war, International Industries and its International Research division became wholly owned subsidiaries of Argus, Inc. The International name then disappeared as an independent corporate identity. IRC’s historical importance rests on its role in making compact AC/DC receivers commercially accessible, popularizing the Kadette name, and using radio manufacturing expertise as a path into the Argus camera business.
