Snell, Willebrord van Royen (1591-1626)


Snell, Willebrord van Royen (1580-1626)


Willebrord van Royen Snell's date of birth is given by various online sources as $13$ June $1580$.

Several source works (notably the 1911 Encyclopedia Britannica) give his birth year as $1591$. This is probably the source of the error in this particular work.
