From an article of that time:

“In 1898, when William Van Berkel manufactured the first slicing machine to make the slicing of cold meats less tiring and more satisfying, he certainly did not think that, in a few years, he would be an international household name. However, his invention met a genuine need and brought real benefit to butchers. It wasn’t long before it became a valued item and soon his slicing machines could be found across five continents. In fact, after only one year, the first factory was already up and running and more than one hundred machines were launched on the Dutch market, with six hundred the following year. (...) It was still, however, within the borders of only one country: the Netherlands. But Van Berkel’s idea, a really brilliant and revolutionary one, deserved much more. 


Very soon, demand for the "Berkel" in foreign markets grew (...). The "Berkel" obtained its first official recognition, being presented at major international fairs. Over the years, Berkel was awarded coveted gold medals at the North-Hansen Fairs (1904), Hamburg (1907), Dusseldorf (1908), Lyon (1913), San Francisco (1916), and Paris (1937). During the First World War the Van Berkel factory also built combustion engines, lathes and planes for the Dutch army, but soon resumed the manufacture of slicing machines and scales. Their first scale was built in 1929. "
