Nikola Tesla

Boudica.

Queen of a British tribe that fought the Romans and won, for a while.

Marcus Aurelius. Philosopher king, savior of Rome, and someone I had fun drawing.

Diogenes

John Brown.

Vlad III, more commonly known as Vlad the Impaler. It's basically the story of Wallachia's complicated relationships with all their neighbours. The real story is so much more interesting than "spooky vampire".

Andrew Wakefield. He's the guy who published a phony study that inspired the Anti-Vax movement. More people need to learn how this always has been a scam.

Christopher Lee.

I recently listened to a podcast about Antonín Švehla. Politician from first Republic (1918-1939) and master of compromise, he was as important as Masaryk but now is mostly forgotten.

Emperor Norton of America

Rani Lakshmibai

I'd elaborate but it would be a really long post. Best to read the wiki page.

Galvarino

James J. Andrews and the great locomotive chase of the US Civil War.

How this hasn’t been made into a movie is beyond me.

Einstein. Or Newton.

Bill Blizzard. I really want to see a solid movie about The Battle of Blair Mountain
