Sam Friedman is Associate Professor in Sociology at the London School of Economics. He has written widely on class, culture and social mobility and is the author of Comedy and Distinction: The Cultural Currency of a ‘Good’ Sense of Humour (Routledge, 2014) and the co-author of Social Class in the 21st Century (Penguin, 2015). He is currently working on two projects. First, he has just finished a book with Daniel Laurison examining the drivers of the class pay gap in Britain’s elite occupations, entitled The Class Ceiling: Why it Pays to be Privileged, which will be published by Policy/University of Chicago Press in late 2018. Second, he has recently begun a new project analysing the entire historical database of Who’s Who – a unique catalogue of the British elite. Drawing on 120 years of biographical data, he is currently examining the changing relationship between Britain’s most elite ‘public schools’ and recruitment into the elite.
