On September 7, 1674 Anton Van Leeuwenhoek was the first person in the world to record this beautiful alga. In letter number 6 to the Royal Society he wrote "About two hours distant from this town their lies and inland lake called Berkelse Mere, who's bottom in many places is very marshy or Boggy. It's water in winter is very clear but at the beginning of or in the middle of summer it becomes whitish and there are then little green clouds floating through it; which according to the saying of the countryfolk dwelling thereabout, is caused by the dew which happens to fall at that time, and which they call honey dew. I took up a little of it in a glass phial and examining this water the next day, I found floating therein divers earthy particles and some green streaks spirally wound serpent-wise after the manner of the copper or tin worms which distillers use to cool there liquors. The circumference of each of these streaks was about the thickness of the hair on one's head"
