Jurgens, but what this could mean is unclear given the absence of Dutch laws governing the definition, ownership, transfer and enforcement of patent rights at the time. It would be more accurate to say that he sold his knowledge of the process. Untroubled by patent restrictions, Jurgens developed Mège-Mouriès's ideas further and began to manufacture and sell margarine, as did another Dutch company under Simon van den Bergh. Both were located in Oss in North Brabant. Jurgens' company eventually became part of Unilever. Mège-Mouriès made very little profit from the invention of oleomargarine, which never became popular in France. Jurgens and van den Bergh created a substantial export industry, selling margarine to England and other countries, as did a number of smaller competitors. In the 1880s there were at least 70 margarine factories in the Netherlands. In 1911 Jurgens exported 111,000 tons of margarine, and Van den Bergh 112,000. Death Hippolyte Mège-Mouriès died on May 31, 1880. He was buried near his wife and son, in Père Lachaise Cemetery in Paris.
