Professor Calculus appears in 91 issues.
Seven archaeologists discover an ancient Inca temple and one by one they fall victim to a curse which puts them in a deep sleep. While the sixth one succumbs to the curse at Tintin's house, professor Calculus is captured and it's up to Tintin and Haddock to rescue him.
Professor Calculus is sent strange blue oranges in the mail and before they have the chance to puzzle over them an intruder tries to steal them. Realizing they are valuable, they head off to Valencia where Professor Calculus recalls a colleague was working on something similar.
Captain Haddock inherits a great ship in Istanbul but is despondent to find it's an old wreck. But when he refuses to sell it to a stranger for a hefty sum and is nearly killed for doing so, he and Tintin realize that it's a clue to a great treasure.
