Kakan Watt, Thomas Watt (1642-1734), malamin lissafi ne, binciken da kewayawa  kuma yana da garantin Baron na Cartsburn. 

Initially, Watt was educated at home by his mother, later going on to attend Greenock Grammar School. There he exhibited an aptitude for mathematics, while Latin and Greek failed to interest him.
