y simple and crude, he started making them long after very elaborate models were available and many important discoveries had been made by them."
"Unfortunately, no early Jansen microscope has survived to the present. The above instrument surfaced in Middleburg, Holland, in the 17th century, and was reported to be an early Jansen made microscope. That microscope now resides in a Middleburg museum. Most historians have come to doubt the origin of the above microscope, but because it corresponds well with the known description of the Royal Jansen microscopes, it is at least very similar to the Jansen microscopes.
Luckily, there was one true Jansen microscope, which survived long enough to be studied. As was customary at the time, the Jansens made several versions of their new invention to give to royalty. We know that they sent one of their microscopes to Prince Maurice of Orange, and one to Archduke Albert of Austria. While neither of these instruments survived to modern times, the later of them was preserved until the early 1600's, when a Dutch diplomat and childhood friend of Zacharias Jansen named Cornelius Drebbel, examined it and recorded his observations.
We would expect a royal presentation microscope to be more ornate and well made than usual, yet it should retain the same mechanical configuration. Drebbel described the royal instrument as being composed of 3 sliding tubes, measuring 18 inches long when fully extended, and two inches in diameter. It was very ornate, with 3 brass dolphins at the end, forming the feet of a tripod. Besides the ornate tripod, this description is quite similar to the microscope found in Holland."
The scientists that are really remembered for revolutionizing the microscope are Robert Brown, Galileo Galilei, Robert Hooke, Ant
