Roger Penn, a British sociologist known for his research on migration, class mobility, and intermarriage, has died at the age of 77. His academic career spanned several decades and institutions, and his work contributed to the understanding of social structures through innovative methodologies.

Born in Lytham, Lancashire, Penn was the son of Olga (née Johnson) and Sidney Penn, a mechanical engineer at the Atomic Energy Authority in Preston. He attended Stratton Grammar School in Biggleswade, Bedfordshire, before enrolling at Jesus College, Cambridge. There, he studied history and later social and political sciences, graduating in 1972. The following year, he advanced his studies in sociology by earning a Fulbright scholarship to Brown University in the United States, where he obtained a master’s degree. He later completed a PhD in sociology at Trinity Hall, Cambridge. His doctoral research culminated in the publication of his book *Skilled Workers in the Class Structure* in 1985.

Penn’s professional tenure began at Lancaster University in 1977, where he eventually became a professor specializing in economic sociology and statistics. In 2012, he joined Queen’s University Belfast, retiring as emeritus professor in 2016. Throughout his career, he engaged in significant collaborative projects, including contributions to the Economic and Social Research Council’s social change and economic life initiative during the mid-1980s.

Among his notable research was an extended case study of Rochdale, a northern English town, where he examined the decline of the textile industry alongside the experiences of ethnic minority populations. Penn was an early adopter of log-linear analysis in sociology, a statistical technique he used to explore the influence of intermarriage on class mobility. He also served as the British coordinator for a comparative international study of migrants across Britain, France, and Germany, publishing several papers through the Sage Social Research Qualitative Dataset series.

In later years, Penn expanded his focus to include the sociology of sport, with particular attention to football culture and graffiti. Football was also a personal passion; he was a devoted supporter of Tottenham Hotspur.

Roger Penn is survived by his wife, three children, and two grandchildren.
