Björn Quanjer is a PhD candidate at Radboud University in Nijmegen. He obtained both his MA and BA in history at the University of Groningen. He is currently working on the ‘giants of the modern world’ project which tries to understand why the Dutch became the tallest people on the planet. More specifically, he is studying how early life conditions (e.g. household composition, disease environment) might have influenced young adult height and growth within the Netherlands of the nineteenth and twentieth century. His wider research interests lie in demographic history, anthropometric history, inequality and heritability.
