What Dutchman was born in 1585 and had a lunar crater Jansen named after him?
Zacharias Janssen
Title: Zacharias Janssen
Passage: Zacharias Janssen (also Zacharias Jansen or Sacharias Jansen) (1585 – pre-1632) was a Dutch spectacle-maker from Middelburg associated with the invention of the first optical telescope.  Janssen is sometimes also credited for inventing the first truly compound microscope.  However, the origin of the microscope, just like the origin of the telescope, is a matter of debate.
Title: Jansen (crater)
Passage: Jansen is a lunar crater in the north part of the Mare Tranquillitatis, named after Zacharias Janssen.  It is located to the east-southeast of the crater Plinius.  The rim of Jansen is low and narrow, with a notch along the western edge.  The interior is relatively level, which may indicate it has been covered by lava.  To the south-southwest a small but prominent crater lies on the crater floor, halfway between the center and the rim, further southeast is a small but prominent crater named Sinas.
Title: Kao (crater)
Passage: Kao is a small lunar crater that is located near the eastern limb of the Moon.  It lies near the southern edge of the Mare Smythii, a lunar mare that continues onto the far side of the surface.  This crater lies to the east-southeast of the crater Widmannstätten.  Less than a crater diameter to the north-northeast is the small crater Tucker.
