The core of this diploma paper was to find and identify as many physicians who were both important individuals as carriers of Zagreb medicine in the 19th and 20th centuries and as active musicians on (string) instruments in chamber ensembles. Furthermore, the aim was to determine possible influences between those two splendid life vocations. Combining a search of existing literature by Antun Goglia, Viktor Boić, and Nada Bezić plus exploring archives of the Croatian Music Institute and Croatian Medical Association has resulted in a lot of predominantly raw data full of names of various physicians and their life paths – challenges in their medical career as well as rehearsals and performances in their free time marked by dedication to chamber music. This was happening mainly in their own homes, which are chronologically arranged, and the Institute halls, but sometimes also in other, public locations. Also, an interesting development of Institute’s Amateur Orchestra has been observed and described. Reasonably, the deterioration of classical music in the narrow sense with time caused a significantly lower interest among the public and thus the number of ensembles has been decreasing. However, the special bond of medicine and (classical) music still remains unquestionable, and their common humanity, virtuosity, and beauty continue to timelessly inspire.
