Zacharias jansenns contribution to the cell theory?
Based on the timeline of the cell theory, father and son, Hans and Zacharias Janssen started produced the first compound microscope. They combined two convex lenses within a tube. This was in the year 1595.
What year was the microscope invented in?
The first microscope was made around 1595 in Holland.
What year was HANS janssen born and what year did he die?
June 25, 1907 in Hamburg February 11, 1973 in Heidelberg
What are Hans and Zacharias Janssen's contributions to cell theory?
As in the evolution of many things, there is usually one who is the "spark" to prepare the way. Zaccharias Janssen was just one of the many building blocks needed. Had he not been inquisitive and inventive, it would have been possibly a lot longer before scientists of the day put together the idea of placing more than one lens in a tube. His works sparked the curiosity of other men such as Galileo to add to and improve upon his own findings. So Janssen was not directly responsible for cell theories. However, others such as Robert Hooke would not have had the platform to work from to develop a cell theory.
What year was the modern day microscope invented?
I t works by the light going from one lens and then getting reflected on to an other len the is converging, Then the light gets reflected into your eye and you see the enlarged image
What year did Hans and Zacharias Janssen's contribution to the cell theory occur?
Hans and Zacharias Janssen invented the compound microscope in 1595.
In what year did Hans and zacharias janssen made their discoverie?
It was the year 1590! They made the first compound microscope!
What year did Hans and zacharias janssen make the first compound microscope?
They discovered the microscope in 1595
When was Hans janssen born?
Hans Janssen was born on November 24, 1590, in the Netherlands. He was a skilled optician and invented the compound microscope with his son Zacharias Janssen in the late 16th century. Their invention revolutionized the field of microscopy and laid the foundation for modern optical instruments.

What year did Hans and Zacharias contribute to the cell theory?
the year I domonated your face
When did Hans and Zacharias Jannsen create the telescope?
The dates are in dispute. The year of the single-lens optical microscope is usually given as 1590 (remarkable, in that Zacharias Jannsen's birth year is sometime between 1580 and 1588), and the year of the telescope as 1608.
What year did Hans and Zacharias Janssen contribution?
Hans and Zacharias Janssen's contribution to the invention of the microscope is believed to have occurred around the late 16th century, in the 1590s. They are credited with creating one of the earliest compound microscopes, which helped pave the way for advancements in the field of microscopy.
When did the first microscope come out?
The first microscope was invented in the late 16th century, around the year 1590. Hans and Zacharias Janssen, Dutch spectacle makers, are credited with creating the first compound microscope.
What year was the microscope invented in?
The first microscope was made around 1595 in Holland.
Who is father of a compound microsecope?
It is difficult to say who invented the compound microscope. Dutch spectacle-makers Hans Janssen and his son Zacharias Janssen are often said to have invented the first compound microscope in 1590, but this was a declaration made by Zacharias Janssen himself during the mid 17th century.Christiaan Huygens, another Dutchman, developed a simple 2-lens ocular system in the late 17th century that was achromatically corrected, and therefore a huge step forward in microscope development.Another favorite for the title of 'inventor of the microscope' was Galileo Galilei. He developed an occhiolino or compound microscope with a convex and a concave lens in 1609. Galileo's microscope was celebrated in the Accademia dei Lincei in 1624 and was the first such device to be given the name "microscope" a year later by fellow Lincean Giovanni Faber.
What year was the first microscope used?
The first microscope was used in the late 16th century, around the year 1590, by Dutch spectacle maker Zacharias Janssen. This early microscope consisted of two lenses in a tube and was a rudimentary form of the magnification instrument.
