As a child, Bobby Seagull would be taken to his local library in East Ham, London, every Saturday afternoon. Without fail. He would get lost in the books there for hours on end, cross-legged on the floor.

These trips would prove life-changing.

In Bobby’s own words during this episode: ‘East Ham Library is the number one reason that I have this career today… it was absolutely pivotal, in terms of making me who I am.’

So much so that today he is officially ‘Libraries Champion’ for CILIP (Chartered Institute of Librarians and Information Professionals), following in the footsteps of Stephen Fry and Mary Beard.

Bobby is known otherwise for his immense range of general knowledge, having gained cult fame via University Challenge. This breadth of knowledge itself in good part stems from those hours spent absorbing the local library’s multitude of wonders.

Alongside libraries and quizzing, he is also evangelical about maths and numeracy, which he continues to teach to secondary school kids and also study part-time at doctorate level in Cambridge, specifically the issue of ‘Maths Anxiety’ (the vexation that so many of us feel when presented with arithmetic, however basic).

Bobby’s passion for these varying pursuits of knowledge is infectious. In this episode, he explains to Ben how we can use numbers to make sense of the world (from the use of stats during elections to Panini sticker books) - as well as touching on his beloved West Ham United, that precious childhood library routine, and how to win a pub quiz.

Joining Ben and Bobby for this episode is Library Development Officer, Deborah Peck. It was recorded in the relatively new East Ham Library building in Newham but also includes a short, touching visit to the nearby site of the former East Ham Library, a seminal home-from-home for both guests during their childhoods.
