Professor Sanders-Hardiman (French: Professeur Sanders-Hardtmut) is a scientific scholar from an un-named European University.
He featured in The Seven Crystal Balls and Prisoners of the Sun as the leader of the ill-fated Sanders-Hardiman Expedition, which bears his name. Like the other members of that expedition he fell victim to an Incan curse, just after he had finished translating the prophecy of that very curse, which put him into a coma. He was eventually awakened after the curse was lifted after Tintin and Captain Haddock traveled to Peru in search of Professor Calculus, and Rupac Inca Hucao destroyed the waxes of the members of the expedition.
