Professor Hector Alembick (French: Professeur Nestor Halambique) is an absent-minded professor whom Tintin meets at the beginning of his adventure, King Ottokar's Sceptre.
He is a scholar who specialises in sigillography. He lives in an apartment at 24 Flyaway Road above his landlady, Mrs. Piggott. He also has a twin brother named Alfred. His identity is stolen by his twin, who imposes himself as Hector as part of the conspiracy to steal Ottokar IV's Sceptre.
He, and Alfred Alembick, were both portrayed by voice actor Peter Wildman in the King Ottokar's Sceptre television episode in the The Adventures of Tintin television episode.
