While holding the corresponding seat in Athens, Schwab continued visiting Greece to offer lectures on his course.
  Meanwhile, he engaged in notable novel research regarding surface catalytic interactions. In the 1955–1956 academic year he was Dean of the Faculty of Natural Sciences of the University of Munich. He retired in 1967 with the title of Emeritus Professor of Physical Chemistry, which he held until his death in 1984.
