How did zacharias janssen contribute to the cell theory?
Zacharias Jansen (c. 1580 - c. 1638) was a Dutch spectacle-maker credited with inventing the first microscope. By the end of the seventeenth century, further developments by Anton van Leeuwenhoek and Robert Hooke allowed Jansenâ??s microscope to be expanded on and this led to the observation of cells under a microscope.
What are Hans and Zacharias Janssen famous for and how did their invention help in the development of the present day cell theory?
In 1950, dutch eyeglass makers, Hans and Zacharias Janssen ( exact dates unknown ), invented the first compound microscopes, by lining up two lenses to produce extra-large images and in doing so they created the compound microscope. They were inventors of the first compound microscope in 1595, which allowed for more in depth studies of cells.
All living things or organisms are made of cells and their products. New cells are created by old cells dividing into two. Cells are the basic building units of life. 5 scientist who contribute to cell theory: Robert Hooke, Matthias Schleiden, Rudolph Virchow, Anthonie van Leeuwenhoek, and Zacharias Jansen. Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. 5 Scientist who contribute:
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…
