Antonie van Leeuwenhoek, Arcana Naturae Detecta (1695)
This is the first drawing ever made of a blood cell. The author of this work, Antonie van Leeuwenhoek, was a Dutch draper and lensmaker, as well as a self-taught scientist. He advanced microscope technology enormously, using his technical skills to create incredibly powerful lenses. It was another 150 years before anyone was able to replicate his findings.
Leeuwenhoek was the first to discover single-celled organisms - he identified bacteria, protozoa and s***m cells. He studied coffee beans, orange seeds and elephant skin and examined rotting meat as well as his own faeces, the dirt between his toes and the plaque on his teeth. Leeuwenhoek shared his findings with the Royal Society of London who sent scientists to corroborate his remarkable discoveries.
This book is on display in our temporary exhibition ‘Rag: A History of Blood’.
