The capability to magnify objects by a factor of up to one million was made possible with the invention of the first transmission electron microscope (TEM) by German scientists Ernst Ruska and Max Knoll in 1931.With the TEM, it was finally possible to view things at the molecular level. Studies were made of the proteins that make up the human body. Metals were also studied. The TEM made all of this possible by focusing a beam of electrons to pass through an object, rather than by focusing light on the object as was done with traditional microscopes. Particles smaller than 200 nm were able to be viewed.
