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.
He invented optical telescope which revolutionized cell theory.
Zacharias and Hans Janssen invented the world's first compound microscope in 1590.
Yes, they were inventors of the first compound microscope. This enabled people to observe cells.
Janssen was the first one to develop a "working" compound light microscope - in 1674, I think

He and Zacharais Janssen discovered the first microscope basicly. It was really just eye-glasses
They created the compound microscope and invented the lenses use by leeuwenhoek. They helped make cells come alive as one of three inventors of the first modern microscope.

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.

They created the compound microscope, allowing people to better analyze and understand the complexity of cells.
Hans and Zacharias Janssen are famous for making the first "simple" microscope which helped to discover cells and that everything is made up of living cells etc. They help us understand the cell structures of a living thing.
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.
