Anton Van Leeuwenhoek
Hooke had discovered plant cells -- more precisely, what Hooke saw were the cell walls in cork tissue. In fact, it was Hooke who coined the term "cells": the boxlike cells of cork reminded him of the cells of a monastery. Hooke also reported seeing similar structures in wood and in other plants. In 1678, after Leeuwenhoek had written to the Royal Society with a report of discovering "little animals" -- bacteria and protozoa -- Hooke was asked by the Society to confirm Leeuwenhoek's findings. He successfully did so, thus paving the way for the wide acceptance of Leeuwenhoek's discoveries. Hooke noted that Leeuwenhoek's simple microscopes gave clearer images than his compound microscope, but found simple microscopes difficult to use: he called them "offensive to my eye" and complained that they "much strained and weakened the sight."
No soap does not use bacteria in its making. One of the objectives of soap using is to get rid of bacteria.
There was bacteria on the loaf of bread he ate, and he got very sick
Viruses are very small and can be considered ultramicroscopic. We were not able to see them with the best light microscopes as we could bacteria (prokaryotes). We have to use an electron microscope to see them as they are that small. This was not available until recently. Leeuwenhoek's microscope was not strong enough to see such small things.

Bacteria were first described by Antonie van Leeuwenhoek in 1676 using a hand made microscope. He called them "animalcules". This word means little animals. The first use of the term bacteria was used by Christian Gottfried Ehrenberg in 1828 in Berlin, Germany.
There's not THE ONE way how bacteria move. some are enabled to diapedeses, others have flagella, others use the flow of their environment to get transported, others use parts of their host cells moving machinery,...
In 1670, Antonie van Leeuwenhoek used a microscope to describe cells in a drop of pond water. He made his own fine quality lens for use in monocular microscopes, and he was the first person to observe bacteria and protozoa. Some of his lenses could magnify objects up to 250X.

Anton Van Leeuwenhoek is considered the father of microscopy because of the advances he made in microscope design and use.

We use microscopes to see tiny things like cells, bacteria, and other microorganisms.
