Dr. Ferdinand E. Knight applied the scientific training he had acquired as a medical student in Vienna, Austria before World War II to the new field when he arrived in the United States as an immigrant in 1938. His father, Dr. Leon Knecht, had been a dentist in Vienna and also ran a dental supply house there. During that period the techniques of dental casting, still practiced today, were first developed.
