Maier-Leibnitz studied physics at the University of Stuttgart and the University of Göttingen. He received his doctorate in 1935, from the University of Göttingen, under the Nobel Laureate James Franck and Georg Joos – Franck had emigrated from Germany in 1933 and his successor was Joos. Maier-Leibnitz was in the field of atomic physics, and he discovered metastable, negative helium ions, which later had applications in particle accelerators.
