With little formal education, Leeuwenhoek worked as a draper for most of his life, using magnifying lenses to inspect the threads of his cloth products.  As an amateur lens-grinder he would begin to construct his own microscopes, eventually creating lenses with a magnification never before seen.  Though not an academic, he wrote letters to the Royal Society of London describing his observations of mold, bees, lice and even his own blood.  In his lifetime he ground over 500 lenses, some from 50X to 200X magnification.
