Willem Einthoven, 'The father of electrocardiography', introduced a new era in the diagnosis and treatment of diseases of the heart. For his contributions he was awarded the Nobel Prize in 1924. This volume is the first book in the English language on Willem Einthoven's life and work. It is based in part on the two Dutch reviews by Einthoven's collaborators, De Waart and Hoogerwerff (1957 and 1946, respectively) and Einthoven's own publications. In addition, extensive use could be made for the first time of the Einthoven archive which contains a large correspondence with Dutch and foreign colleagues and friends, along with their evaluations of Einthoven's work and personality. This book provides an interesting and unique insight into Einthoven's work, his personality, and his relation to his contemporaries. It is also a valuable document about an episode which has been of great importance in the development of modern medicine.Snellen, H.
