Drusus_1
Drusus, Nero Claudius (38 b.c. to 9 A.D.), was the brother of the Emperor Tiberius. He extended the Roman sway in Germany to the Ocean and the Elbe, and received the title "Germanicus," which, however, is applied more particularly to his son. He was the father of the Emperor Claudius by Antonia, daughter of Mark Antony.
