In German, I think their full name is Laugenbrezel. The full name may not be much used[1] colloquially, because it's implied -- but bread rolls made the same way are definitely called Laugenbrötchen.
"Lauge" is German for "lye". They're called that because they're made with it.
[1]: Though when I switched my phone keyboard to German just now to test it out, the predictive spelling corrector suggested "Laugenbrezel", not "-brötchen", when I'd got as far as "Laugenb".
