nt.number theory – Reference for behavior of Artin $L$-functions at $Re(s) = 1$

Would anyone know a reference that proves the basic facts about Artin $L$-functions at $Re(s) = 1$? Namely, the non-vanishing and holomorphicity for non-trivial characters.

I assume this was done in Artin’s original paper, but a modern source would be most welcome.
