Jacob Metius

Jacob (or Jacobus) Metius (died between 1624 and 1631), Dutch instrumentmaker and optician. He was born in Alkmaar and was the brother of Adriaan Adriaanszoon (simply called Metius). A specialist in grinding lenses, he claimed to have invented the telescope. 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 He applied for his patent only a few weeks after Hans Lippershey.

In his Mathematical and Philosophical Dictionary (1795), Charles Hutton writes: "In 1620, James Metius of Alcmaer, brother of Adrian Metius who was professor of mathematics at Franeker, came with Drebel to Middleburg, and there bought Telescopes of Jansen's children, who had made them public; and yet this Adr. Metius has given his brother the honour of the invention, in which too he is mistakenly followed by Descartes."http://archimedes.mpiwg-berlin.mpg.de/cgi-bin/toc/toc.cgi?dir=hutto_dicti_078_en_1795;step=textonly;corpus=&page=1291&n=1291

The States General voted Jacob Metius a small award, although it ended up employing Lippershey to make binocular versions of the telescope.
