Difficult to say, there seems to have been several Dr. Hurtas in the Austtri-Hungarian Empire: Checking Google Books - Dr. Ignaz Hurta (1854) Doctor for Mines in Czernowitz; - Dr. Johann Hurta (1853), personal doctor of the Archbishop (Princeps Primas) of Hungary (Béla Bartakovics?) Did Geschwind know the former, or did he honour the latter, or someone else?
