The atom probe was introduced at the by Erwin Wilhelm Müller and J. A. Panitz.
Erwin Wilhelm Müller (or Mueller) (June 13, 1911 – May 17, 1977) was a German physicist who invented the Field Emission Electron Microscope (FEEM), the Field Ion Microscope (FIM), and the Atom-Probe Field Ion Microscope.
The Field ion microscope (FIM) was invented by Müller in 1951 It is a type of microscope that can be used to image the arrangement of atoms at the surface of a sharp metal tip.
Field-emission microscopy (FEM) is an analytical technique used in materials science to investigate molecular surface structures and their electronic properties.
John A. Panitz is Emeritus Professor of Physics at the University of New Mexico in Albuquerque.
