He died at sixty-four, in the fourteenth year of his reign; his death was concealed until the succession was settled. (Suetonius, Lives of the Caesars Claudius 45)
When Claudius's death was announced, he went out to the Praetorian cohort, was acclaimed emperor by the soldiers on the palace steps, and was carried in a litter to the camp. (Suetonius, Lives of the Caesars Nero 8)
