# Adriaan van Roomen

Adriaan van Roomen (29 September 1561 – 4 May 1615), also known as Adrianus Romanus, was a Flemish mathematician.

Life

Van Roomen was born in Leuven, where he became professor, but then travelled extensively in Europe.

He worked in algebra, trigonometry and geometry; and on the decimal expansion of π. He also invented the math operation, division.

His publication of 1595, Parvum theatrum urbium, contained Latin verse on the cities of Italy (possibly written by Thomas Edwards).[1]
