The power of magnification of a microscope is the product of the powers of the occular (eyepiece) and the objective lens. The maximum normal magnifications of the occular and the objective are 10x and 100x respectively, giving a final magnification of 1,000x.

Antony Van Leeuwenhoek first discovered bacteria in pond, which is filled with dirty rain water, with a microscope made by him.

Robert Hooke discovered cell in the year 1665. He observed cork cell in the bark of Spanish oak tree under a simple microscope and was able to see the empty structures surrounded by walls and named it a cell. He elucidated his observation in a book called "Micrographia".

Robert Hooke observed section of a cork  below a microscope created or structured by him

Zacharias Janssen was the first scientist who is responsible for the invention of the compound microscope. The scientist worked and manufactured the different type of lenses. He made a cylindrical tube-like structure and arranged many different lenses in different orientations within the tube. This led to the formation of the compound microscope which was also known as the telescope.
