Adriaan Adriaanszoon, called Metius, (December 9, 1571-September 6, 1635), was a Dutch geometer and astronomer. He was born in Alkmaar. The name Metius may come from the Dutch word meeten ("measuring"), and therefore may mean something like "land-measurer" or "surveyor."

Metius' father, Adriaan Anthonisz, was also a mathematician, land-surveyor, cartographer, and military engineer who from 1582 served also as burgomaster of Alkmaar.

Metius' brother, Jacob Metius, worked as an optician. Also born in Alkmaar, Jacob died between 1624 and 1631. Not much of him is known besides the fact that in October 1608, the States General discussed his patent application for a device for "seeing faraway things as though nearby," consisting of a convex and concave lens in a tube, and the combination magnified three or four times.http://galileo.rice.edu/sci/instruments/telescope.html

Metius attended a Latin school in Alkmaar and studied philosophy in 1589 at the University of Franeker, which had been recently founded. He continued his studies at Leiden in 1594, where he studied under Snellius. He worked for a brief time under Tycho Brahe on the little island of Hven, where Brahe had built two observatories, and subsequently worked at Rostock and Jena, where he gave lectures in 1595. Subsequently, he returned to Alkmaar and assisted his father for a time as a military engineer inspecting fortifications, and also worked as a teacher of mathematics at Franeker in Frisia, his teaching especially geared towards the training of surveyors.

At the University of Franeker, he was appointed 1598, appointed professor extraordinarius in 1598, and served from 1600 to 1635 as professor ordinarius of mathematics, navigation, surveying, military engineering, and astronomy. He was permitted to teach in the vernacular instead of Latin. He served as rector of the university in 1603 and 1632.
