Willebrord Snellius[1][2] (born Willebrord Snel van Royen)[3] (13 June 1580[4] –30 October 1626) was a Dutch astronomer and mathematician, commonly known as Snell. His name is usually associated with the law of refraction of light known as Snell's law.[5]

In 1615, Snellius, after the work of Eratosthenes in Ptolemaic Egypt in the 3rd century BC, probably was the first to use triangulation to do a large-scale arc measurement for determining the circumference of the earth.[7][8] He was helped in his mea

Willebrord Snellius[1][2] (born Willebrord Snel van Royen[3]) (1580[4] – 30 October 1626, Leiden) was a Dutch astronomer and mathematician. In the west, especially the English speaking countries, his name has been attached to the law of refraction of light for several centuries, but it is now known that this lag was first discovered bygd Ibn Sahl in 984. The same law was also investigated by Ptolemy and in the mittpunkt Ages bygd Witelo, but due to lack of adequate mathematical instruments (trigonometric functions) their results were saved as tables, not functions.
The lunar crater Snellius is named after Willebrord Snellius.
