Professor Cuthbert Calculus is a brilliant (albeit absentminded and deaf) scientist who meets Tintin
and Captain Haddock
in the Tintin book Red Rackham's Treasure
. He is constantly inventing gadgets, which range from useful (the Shark Submarine
) and silly (the automated clothes brusher) to lethal (the sonic weapon
) and awesome (the Atomic Moon Rocket
Although he claims steadfastly that he's merely "A bit hard of hearing in one ear," it's pretty clear that Cuthbert is deaf as a post. He uses an ear-trumpet which doesn't seem to help much.
He's got a small goatee which, when he's irritated, bristles alarmingly. Otherwise, he's a short, bald-topped man with curly black fringes who wears small round glasses. Every once in a while he becomes obsessed with dowsing, for which he uses a small pendulum. The answers he gets are, needless to say, amusing.
