American Physicist
My first project was to build an ionization gauge control circuit for Professor Edgar Everhart's Cockcroft-Walton accelerator. In those days, vacuum tubes were the active components in electronic circuits. I can still recall the warm orange glow of the vacuum tube filaments and the cool blue glow of the thyratron tubes.

Carl D. Anderson
American Scientist
Measurements of the specific ionization of both the positive and negative particles, by counting the number of droplets per unit length along the tracks, showed the great majority of both the positive and negative particles to possess unit electric charge.

American Physicist
Simultaneous recording with superimposed ionization chambers and Wilson chambers, ionization chambers and sets of counting tubes, has not yet been carried out.

Johannes Stark
Physicist
The removal of an electron from the surface of an atom - that is, the ionization of the atom - means a fundamental structural change in its surface layer.
