Deinarchus

Deinarchus, (c.360–c.290 BC), a distinguished Greek orator, Corinthian by birth, who lived in Athens. Not being an Athenian citizen he was debarred from addressing the assembly, but he composed a large number of speeches for others, including a speech Against Demosthenes connected, like his other two surviving speeches (Against Aristogeiton and Against Philocles), with the Harpalus affair (see DEMOSTHENES (2) 1). Three other speeches surviving in the manuscripts of Demosthenes have sometimes been attributed to Deinarchus: Against Boeotus II, Against Theocrines, and Against Mantitheus.
