Paddy O'Connell travels the country with his dog, Bob, talking to the people he meets.

Now they've arrived in one of the most diverse areas in Britain - the east London Borough of Newham.

It was once home to Tommy Flowers, inventor of the Bletchley Park codebreaking machine, Colossus.

Paddy visits Flowers' former college and wonders why this local hero isn't as well remembered as his colleague Alan Turing.

Producer: Jo Coombs

A Loftus production for 91福利社 Radio 4 first broadcast in December 2016.
