Hooke was the first to use a compound microscope, while Leeuwenhoek was the first to use a simple microscope. He also made improvements on these designs that made them more powerful.
Hooke was the first to observe cells, while Leeuwenhoek was the first to observe bacteria. He also invented an improved method for staining cells with dye so they could be seen more easily under magnification.
