Compound microscopes have more than one lens. The first (objective) lens magnifies the object to produce an image. Subsequent lenses magnify an image produced by a previous lens.
Leeuwenhoek's "microscope" had only one lens -- simple magnification only.
The main disadvantage of the Leeuwenhoek microscope was that it only had one lens. On the other hand, it had much better magnification and clarity than the compound microscopes that were being used at that time. The inventor was Antony Van Leeuwenhoek.
Antony Leeuwenhoek's job prior to working on the microscope was being a shopkeeper.

improvement of the microscope
The first compound microscope had multiple lenses for magnification and was generally larger and more complex in design. Anton van Leeuwenhoek's microscope, on the other hand, was a simple single-lens design, with a tiny but powerful lens that enabled him to see tiny organisms that were previously unseen.

Somewhere in Holland. He is credited with making the first microscope.
Antoine van Leeuwenhoek was a Dutch scientist who worked on microbiology. He's noted not for inventing the microscope, but for improving it. In one instance, when he presented a microscope to Peter the Great, he called it an 'eel-viewer'.
The scientist who is credited with discovering the existence of bacteria is Antonie van Leeuwenhoek. He used a microscope to observe microorganisms, including bacteria, for the first time in the 17th century.
It was he who discovered bacteria
The first scientist credited with the invention of the microscope is Zacharias Janssen, a Dutch spectacle maker, around the late 16th century. His compound microscope had two sets of lenses that allowed for greater magnification than simple magnifying glasses.
