content: A few makers of calculating machines survived into the era of electronic calculators. Monroe Calculating Machine Company, formed in New Jersey in the early twentieth century, initially made stepped drum calculating machines. A few years after it became a division of Litton Industries in 1958, the firm began to sell desktop electronic calculators. By the mid-1970s, it sold handheld electronic calculators as well. These were imported from Asia.
