GLASSER returned to the Cleveland Clinic as the Head of the Department of Biophysics. He and his staff attempted to apply physical laws to living processes; among other things they analyzed the way different kinds of rays effect tissues
IN addition, Glasser worked on his greatest success: the condenser dosimeter, which he developed together with his colleagues Seitz, an engineer, and Portmann, a radiation therapist. It's precursor the "Fricke-Glasser X-Ray Dosimeter" had some serious disadvantages that were improved in the new apparatus. Attending the 28th annual meeting of the American Roentgen Ray Society in Montreal, Glasser presented their invention for the first time to the public.

BESIDES his work as the Head of the Department, Glasser was interested in the work and life of Wilhelm Conrad Roentgen, the discoverer of x-rays. Since 1929 Glasser had written hundreds of letters to x-ray pioneers and contemporaries of Roentgen all over the world in order to gather information and to clarify misconceptions. He presented the results of his research in a biography of Roentgen published first in German in 1931 and two years later in English.
