label: Description
content: Carl Von Linde’s refrigerators were some of the earliest compressed-ammonia refrigerators to be sold on an international scale due to their reliability and efficiency. After their creation in the 1870s, Linde’s machines supplanted ice as the main way to keep food and drinks cold in breweries and other food industries, and they also found use in other industrial process requiring cold temperatures.
label: Description
content: Frederick W. Wolf was a German mechanical engineer who moved to the U.S. in 1866 and obtained the rights to manufacture and sell Linde’s machines in 1878, eventually creating his own company to do so. By the time of his death in 1912, the American Society of Mechanical Engineers claimed that Wolf’s company had built 1,200 machines and that Wolf was “the father of the refrigerator industry in the United States.” In 1913, Wolf’s son, Fredrick Wolf Jr., invented the DOMELRE (short for DOMestic ELectric REfrigerator), one of the first successful mass marketed electric refrigeration units made for domestic uses.
