To test it, Ruska first boiled electrons off a tungsten filament, the same kind of filament you'd find in an incandescent light bulb.

By 1931, Ruska and his colleague, Max Knoll, used this kind of design to build the first working electron microscope.

By the mid-1930s, Ruska had gotten the TEM way past 10,000 times magnification.

Luckily, Ruska's electron microscope wouldn't stay stuck in the realm of insects and bacteria forever.

And it was interesting that the critic, Ruskin, who was the major British critic at the time, basically accused him of flinging paint

Fortunately, a copy of his paper fell into the hands of an eager young PhD student, Ernst Ruska.
