While Bob originated in the United Kingdom, the show also became hugely popular in the United States, where he was played by voice actor William Dufris.
Dufris was the American voice of Bob for the first nine seasons, before a change of creative teams behind the scenes.
To an entire generation, though, he will be one of the most recognized and beloved voices of their childhood.
Dufris also worked extensively in radio and audio dramas (including one for Spider-Man, where he voiced the title character), and was the narrator of numerous audiobooks.
