Well this is awkward. From Johann Georg von Hahn’s Wikipedia page:

In 1847, Hahn was named Austrian consul in Ioannina. He was transferred to Syros in 1851, and from 1869 was the consul-general in Athens. He is considered the founder of Albanian studies.

Unfortunately the page on Albanian studies it links to names someone else as the father of Albanology. It then lists other famous founders (no sign of Johann). He doesn’t even make the list of important Albanologists :S
