Caius Suetonius Tranquillus (c.71-c.135), Roman scholar and official.
Suetonius was a scholar of various antiquarian interests, best known for his vitae caesarum, commonly referred to as Life of the Twelve Caesars. He held several imperial posts, the last one as ab epistulis to Hadrian, responsible for all imperial correspondence, but was dismissed later for unknown but much conjectured reasons. He was a biographer rather than a historian. More at the above link at livius.org.
Anthony Birley, in Hadrian, The Restless Emperor, suggests that "...Suetonius' Divus Augustus incorporates what can be read as Hadrian's interpretation of Augustan policy, rewriting history indeed." (The related endnote references E.M. Smallwood, Documents Illustrating the Principates of Nerva, Trajan and Hadrian, Cambridge 1966).
