Zernike obtained a doctorate from the University of Amsterdam in 1915. For the next fifty years he corresponded with the Royal Society; build microscopes that magnified over 200 times, with clearer and brighter After seeing Hooke’s illustrated and very popular book Micrographia, van Leeuwenhoek learned to grind lenses some time before 1668, and he began building simple microscopes. He started making simple microscopes he could observe with. Several of Leeuwenhoek's predecessors and contemporaries, notably Robert Hooke in England and Jan Swammerdam in the Netherlands, had built compound microscopes and were making important discoveries with them.
