Fregattenleutnant Friedrich Lang--Info.?

[josquin]

Fregattenleutnant Friedrich Lang is one of the two Great War aces of the
Austro-Hungarian Navy, but there is no biographical information available
for him as there is for Gottfried Banfield. I request any biographical details
for Lang, including birth/death dates and locations, prewar life, details of
his military service at the 3 naval air stations where he was posted, and
his postwar life. Almost 2 years passed between his 2nd and 3rd victories,
a rather distinctive interval, so I would like to learn more about his Great War
service as well as his life. Any information will be appreciated.
