Antony van Leeuwenhoek, de ontdekker der infusorien, 1675-1875

Antony van Leeuwenhoek’s tiny lenses opened a whole universe that had been invisible to ordinary eyes. This biography follows his restless curiosity from a modest cloth‑merchant’s workshop to the moment he first saw living organisms swimming in a drop of water. Listeners will hear how his meticulous observations laid the foundation for microbiology and sparked an international surge of fascination with the unseen world.

The narrative also captures the spirit of the 1874‑75 celebrations that marked two centuries since his discovery. Dutch and German scientific societies gathered to honour him, prompting the publication of a refreshed edition that includes rare portraits, a faithfully reproduced medal, and fresh annotations drawn from recently uncovered correspondence. Among the lesser‑known details are references to Johan Ham’s claim to the discovery of spermatozoa and a lively debate over whether Leeuwenhoek first saw the infusoria in April or September of 1675.

By weaving personal anecdotes with the broader scientific climate of the 17th century, the book offers a vivid portrait of a man whose simple microscope changed how we view life itself.
