Think you'll find that Antonis and Nikalaos Simigdales set up Aegean in 1987 (although they had been operating ad-hoc flights and trying to set up a scheduled airline for years in the face of opposition by OA and the Greek government - mind you weren't they one and the same?).
The codeshare bit was to show that other renowned airlines are happy to do business with Aegean - so they can't be that bad?
Anyway if you want to read more on Aegean see here:
