actor chiefly remembered for his will, in which he bequeathed property to found a home for aged and impoverished actors and also money to provide wine and cake in the green room of Drury Lane Theatre on Twelfth Night, a ceremony that was still performed more than 200 years later.

Baddeley is said to have been a cook to the actor Samuel Foote (Foote, Samuel). Later, as a valet, he acquired a familiarity with foreign languages and manners that made him especially successful in “broken English” parts. In 1761, described as “of Drury Lane Theatre,” he was seen at the theatre in Smock Alley, Dublin, as Gomez in Dryden's Spanish Fryar. Two years later he was a regular member of the Drury Lane company in London. He remained at Drury Lane and the Haymarket until his death. Baddeley was the original Moses in Sheridan's School for Scandal, which had its first performance at Drury Lane in May 1777.
