Does anybody know what were the design specs of Galileo's original telescope, and what was the name of the lens maker in Flanders from whom he obtained it? |

Galileo improved the telescope though, and created scopes which magnified up to some 20 times. and what was the name of the lens maker in Flanders from whom he obtained it?

Hans Lippershey I noticed that Fred Watson, in his 2004 book _Stargazer: The Life and Times of the Telescope_, deliberately spells the name Lipperhey. I can deal with a name having an alternate spelling, but I'd expect Lippershey to be pronounced differently than Lipperhey. Or is this a case where the "s" is silent in Dutch? -- ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Mark Gingrich San Leandro, California |

See http://cnx.org/content/m11932/latest/ Galileo built his own telescopes, or had them built. Hans Lippershey was given a patent on the telescope by the Dutch government in the early 1600s, but didn't provide one to Galileo. The History of the Telescope by H. C. King, listed in the bibliography, has been reprinted by Dover Books and is available from book sellers. Bud |

Being Dutch, I have heard neither name around here , and they sound german/english. |

The Winkler Prins, a Dutch encyclopedia, says Johannes Lipperhei or Lippershey, also Joannes Laprei. The i to y change is common, but I never noted a silent s in Dutch. My guess is that Johannes was still experimenting with a family name. Joachim. -- Joachim Verhagen WWW http://www.xs4all.nl/~jcdverha/ (Science Jokes) |

It is reproduced at http://cnx.org/content/m11940/latest/ but it is hard to make out. Lipperhey was German by birth. Bud |
