George Bogdan

After returning home, he began work as a doctor at Sfântul Spiridon Hospital and as a teacher at the National College, where he offered a course on hygiene.

The same year, he was named dean of the medical faculty and a member of the university senate.

He taught that doctors should follow principles of honesty, modesty and deference; that they are morally responsible for their actions; and that irresponsibility is "a sad privilege of the sick and the insane".

[1] He wrote a five-volume course on forensic medicine; this was considered the field's most up-to-date Romanian text at the time.

An active participant in international hygiene congresses, he focused on health education and preventive medicine.
