LifeAnthonisz served as burgomaster (mayor) of Alkmaar in the Netherlands from 1582.[4] Adriaan fathered two sons, and named them both Metius (from the Dutch word meten, meaning 'measuring', 'measurer', or surveyor). They each became prominent members of society.[5] Adriaan Metius (9 Dec 1571 – 6 Sep 1635) was a Dutch geometer and astronomer. Jacob Metius worked as an instrument-maker and a specialist in grinding lenses and applied for patent rights for the telescope a few weeks after Middelburg spectacle-maker Hans Lippershey tried to patent the same device.[6] CareerIn 1585 Anthonisz discovered that the ratio of a circle's circumference to its diameter, later called pi, approximated the fractional value of {{math|{{sfrac|355|113}}}}. His son Adriaan Metius later published his father's results, and the value {{math|{{sfrac|355|113}}}} is traditionally referred to as Metius' number'.[7][8] He is regarded as one of the first military engineers to apply the principles of the Dutch fortification system.[9] Some of his professional accomplishments included mapping the Berger lake and expanding and fortifying Naarden and Muiden.[10] References1. ^{{cite book|author=Charles Joseph Singer|title=Studies in the History and Method of Science: Singer, Charles.
