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.
Zacharias Janssen was born in The Hague. Local records seem to indicate he was born in 1585 although a date of birth as early as 1580 or as late a 1588 are also given. His parents were Hans Martens (who may have had the occupation of a peddler) and Maeyken Meertens, both probably from Antwerp, Belgium. He grew up with his sister Sara in Middelburg, at the time the second most important city of the Netherlands. He was known as a "street seller" who was constantly in trouble with the local authorities.
He himself stated he was born in The Hague on the marriage file of his first marriage, with Catharina de Haene, on October 23, 1610. When this file was refound by Cornelis de Waard in 1906, De Waard found the following excerpt: Sacharias Jansen, j.g. uut Den Haag, "Zacharias Jansen, bachelor from The Hague" Before, it was often thought that Janssen was a native of Middelburg. In 1612, Zacharias and Catharina had a son they named Johannes Zachariassen.
Humans have long known that glass bends light. However, it took us awhile to figure out that stacking lenses in a tube would open up a whole new world to science, finally allowing us a peek at the microscopic.

El microscopio (del prefijo micro- y el sufijo -scopio, 'muy pequeño', y 'ver') es un instrumento que permite observar objetos que son demasiado pequeños para ser vistos a simple vista. El tipo más común y el primero que se inventó es el microscopio óptico. Se trata de un instrumento óptico que contiene dos o más lentes que permiten obtener una imagen aumentada del objeto y que funciona por refracción. La ciencia que investiga los objetos pequeños utilizando este instrumento se llama microscopía. Microscopio compuesto fabricado hacia 1751 por Magny. Proviene del laboratorio del duque de Chaulnes y pertenece al Museo de Artes y Oficios, París. El microscopio fue inventado por Zacharias Janssen en 1590. En 1665 aparece en la obra de William Harvey sobre la circulación sanguínea al mirar ...
