Who are historical figures who deserve a better (or any!) biography? Could be anyone from a 20th century figure to someone further back in history.

In Herodotus's 'The Histories' there is a conspiracy to murder the magus who usurped the Persian throne (III. 79-84)

After decapitating the magus, three men debate the future of the Persian empire: democracy (Otanes) v oligarchy (Megabyzus) v monarchy (Darius)

Otanes strikes the greatest deal ever; few know about him

OMG — he’s a footnote in the book I just started (Arendt’s ‘The Human Condition’)
