How many microscopes did Leeuwenhoek make and what happened to them?
The lenses may or may not have been made by Leeuwenhoek. As with the two disputed single-lens microscopes, their provenance is not completely certain. More than 90% of the microscopes that we know Leeuwenhoek made have not survived….Since 1875.

Did Anton van Leeuwenhoek make a microscope?
Antonie van Leeuwenhoek used single-lens microscopes, which he made, to make the first observations of bacteria and protozoa. His extensive research on the growth of small animals such as fleas, mussels, and eels helped disprove the theory of spontaneous generation of life.
How did Leeuwenhoek make his microscopes?
Leeuwenhoek produced these lenses by chipping away the excess glass from the thickened glass droplet that forms on the bottom of a blown-glass bulb. These incredible lenses had a thickness of about one millimeter and a radius of curvature of 0.75 millimeter.
When did Anton van Leeuwenhoek make his own microscope?
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. This jack-of-all-trades became a master of one. His simple microscope design used a single lens mounted in a brass plate.
How many times Leeuwenhoek microscope magnify the object?
The microscopes manufactured by Antonie van Leeuwenhoek (1632-1723) featured a single lens and a spike upon which the sample was skewered. The microscopes of Van Leeuwenhoek’s contemporaries magnified objects approximately 30 times, but his microscopes were up to 10 times more powerful.
