Jacob (Jacobus; sometimes James) Metius (b. after 1571, Alkmaar – d. 1624-1631, Alkmaar), was a Dutch instrument-maker and a specialist in grinding lenses. He was born in Alkmaar and was the brother of Adriaan Adriaanszoon (simply called Metius). He is one of three people associated with the invention of the telescope, the other two being Hans Lippershey, and Zacharias Janssen. Not much of him is known besides his 1608 patent application for the invetion. He died in Alkmaar between 1624 and 1631. Metius may have made many inventions but kept them secret. Before his death he destroyed them all to prevent anyone else from claiming them.
