Overview
Victor Technology LLC, also known as Victor Calculator, is an American supplier of printing, scientific, financial, and basic calculators, together with desktop accessories. The company is headquartered in Bolingbrook, Illinois, and sells primarily through independent office-supply dealers in the United States, Canada, and Puerto Rico, with later distribution activity extending into Latin America. The business traces its origins to Victor Adding Machine Company, which was operating in 1918. Carl Buehler became involved after a Victor salesman accepted his proposed $100 purchase as an investment in the company. Buehler joined the board in September 1918 and became president three months later. Victor introduced its first adding machine, the Model 110, in 1919. After Buehler's death in 1932, his son A. C. Buehler assumed control and continued a strategy centered on reinvestment, product development, manufacturing capability, sales coverage, and employee relations. Victor expanded substantially during the twentieth century. During the Second World War it produced military-related equipment, including an aircraft compass, a B-24 bomber turret gunsight, and the Norden bombsight. After the war, it became a major specialist in adding machines and reported reaching more than one million units sold by 1952. In 1953, the company entered cash registers by acquiring McCaskey Register Company. A 1961 merger with Comptometer Corporation broadened its calculating-machine and office-technology capabilities. The combined business experimented with electronic products, including the large Victor 3900 electronic calculator, introduced in 1965, and later developed electronic calculators, printers, programmable calculators, and cash registers. Kidde acquired the company in 1977 and renamed it Victor Business Machines. Under Kidde, Victor also entered the microcomputer market. Through an arrangement involving Sirius Systems Technology, it obtained domestic distribution rights for the Sirius 1, an Intel 8088-based computer compatible with MS-DOS and CP/M-86. Victor marketed the system as the Victor 9000. The computer became particularly successful in Europe, although rapid expansion and weaker-than-expected sales later contributed to financial difficulties. Victor Technologies entered Chapter 11 bankruptcy proceedings in February 1984. Datatronic AB acquired 90 percent of Victor Technologies in an agreement reached in 1984 and completed in February 1985. The company subsequently emphasized calculators in the United States and computers in Europe. The computer division was sold to Tandy Corporation in 1989, leaving the U.S. calculator business as the core of the remaining Victor operation. In 1991, members of Victor's U.S. management acquired the assets through DMJCO, Inc. In 2006, those assets were acquired by Jordan Feiger and John Ringlein, and the company adopted the name Victor Technology LLC. In its modern phase, Victor has concentrated on business and financial calculators, printing calculators, basic and scientific models, and office accessories. Its V12 financial calculator, introduced in 2007, was positioned against established financial-calculator products. The PL8000 printing calculator followed in 2008 with features including an alphanumeric display and printer, guided prompts, a loan calculator function, reprinting, personalized text messages, and a help key. Victor expanded into premium desk accessories with the Midnight Black Collection in 2012, later adding other finishes. In 2015, it became a source for Sharp calculators in the United States and Latin America. The company remains an active calculator and desktop-accessories brand rather than the diversified office-computing business it operated during parts of the twentieth century.
History
Victor's history began with Victor Adding Machine Company in 1918. Carl Buehler became a director after converting an intended adding-machine purchase into an investment and became president before the end of that year. The first Victor adding machine, Model 110, appeared in 1919. Buehler's son A. C. joined the company as vice president of operations in 1921 and took control after his father's death in 1932. The company developed a substantial manufacturing and sales organization around adding machines. During the Second World War, it applied its production capabilities to military equipment, including an aircraft compass, a B-24 bomber turret gunsight, and the Norden bombsight. In the postwar period, Victor strengthened its research, manufacturing, distribution, and service operations. By 1947 it was described as the world's largest exclusive adding-machine manufacturer, and it surpassed one million units sold five years later. Victor diversified into cash registers in 1953 through the acquisition of McCaskey Register Company. During the 1960s it moved toward electronic calculation and broader office technology. The 1961 merger with Comptometer Corporation combined Victor's adding-machine business with calculating machines and the Electrowriter telecommunications device. The Victor 3900, introduced in 1965, was an early electronic desktop calculator using MOS integrated-circuit technology, although its size and manufacturing difficulties limited its commercial life. Victor also distributed Hugin cash registers and had developed a broad product range by the late 1960s. Electronic product development accelerated in the 1970s. Victor introduced the 1800 series in 1971, an electronic dot-matrix printer in 1973, programmable calculators in 1974, and electronic cash registers in 1975. Kidde acquired the company in 1977 and renamed it Victor Business Machines. The new ownership encouraged exploration of emerging office technologies, including microcomputers. Victor secured domestic distribution rights for Sirius Systems Technology's Sirius 1 and sold it as the Victor 9000. The system was an Intel 8088-based computer capable of running MS-DOS and CP/M-86 and achieved notable European sales. The computer expansion was followed by financial strain. Rapid growth in staffing and branch infrastructure coincided with sales below expectations. Victor Technologies entered Chapter 11 proceedings in February 1984 while continuing to process office-equipment and computer orders. Datatronic AB agreed to acquire 90 percent of the company in August 1984, completing the purchase in February 1985. Victor then focused its U.S. activities on calculators and its European activities on computers. Proventus AB later became associated with the parent company, and the Victor Computer Division was sold to Tandy Corporation in 1989. The remaining U.S. calculator operation was purchased in May 1991 by DMJCO, Inc., formed by members of Victor's U.S. management. In 2006, Jordan Feiger and John Ringlein acquired DMJCO's assets and renamed the business Victor Technology LLC. The modern company has concentrated on printing, financial, scientific, and basic calculators, while also developing desktop accessories. The V12 financial calculator appeared in 2007, the feature-rich PL8000 printing calculator in 2008, and the Midnight Black Collection of premium desk accessories in 2012. In 2015 Victor became a source for Sharp calculators in the United States and Latin America. Its present identity is therefore rooted in the legacy of Victor's adding-machine business but focused on calculator products and adjacent office accessories.
