The “Heemskerk” name comes from the explorer Jacob van Heemskerk. See quotation below fromthisresource on Brass candlesticks by Jim Melchor and Tom Newbern:
In 1596, Jacob van Heemskerk led a mercantile voyage from the Netherlands in an effort to find a northern passage to China. The fleet ran into trouble in the Arctic Ocean and was forced to spend the winter on the archipelago of Nova Zembla in the Arctic north of Russia. The voyage was abandoned, and a large cache of goods, including pewter candlesticks, was left behind. This cache was found in the mid 1870s and returned to the Netherlands. In Figure 15a, Heemskerk is the style of stick associated with the candlestick on the left and the rare taperstick in the middle. These copper-alloy examples are usually assumed to be Dutch, but Michaelis and others believe they were native to both England and the Netherlands during the 17th century. The mid-drip candlestick on the right, however, is peculiar to England.
