Microbiologist Antoni van Leeuwenhoek's groundbreaking observations of single-celled life forms in 1674 are detailed in a new biography by historian Geertje Dekkers. The book, "Myriad, Microscopic and Marvellous," published by Reaktion in 2025, recounts van Leeuwenhoek's examination of lake water under a microscope, revealing bacteria and protozoa racing in all directions. Dekkers highlights that van Leeuwenhoek also accurately described red blood cells, capillaries, striated muscle fibres, spermatozoa, and the crystalline lens of the eye.
Van Leeuwenhoek's contributions were highly valued by the scientific community of his time. Upon his death in 1723, the UK Royal Society acknowledged the loss of its most valuable correspondent, according to Dekkers' biography.
Another book, "Naturekind," explores the interconnectedness of humans and the natural world. Anthropologists Melissa Leach and James Fairhead, in their 2025 Princeton University Press publication, delve into the study of meaning in sign systems, known as semiotics, to examine human encounters with various living beings, including chickens, horses, bees, bats, and plants.
Leach and Fairhead consider communities and cultures through which humans are inextricably linked with wider life, encompassing forests, seas, soils, and cities, which contain both living and non-living entities. They develop biosemiotics by linking biological findings to social and cultural interpretations. This approach seeks to understand how humans perceive and interact with the natural world, considering the complex relationships between living organisms and their environments.
