In Study of British Genius, Ellis delves into the psychological and anthropological traits that define genius in the British Isles. Drawing from a rich tapestry of information sourced from the Dictionary of National Biography, he explores a myriad of topics, including ancestral heritage, geographical distribution, professions, and the health and morbidity of the eras most distinguished men and women. This insightful work also posits a provocative theory that large cities may hinder the emergence of high achievers and negatively impact national health. (Summary by Leon Harvey)
