Synopsis
Potato: A History of the Propitious Esculent by John Reader is a comprehensive and engaging exploration of the potato’s profound impact on human history, tracing its journey from a wild Andean plant to a global staple that has shaped societies, economies, and populations. The book, also published as The Untold History of the Potato and Propitious Esculent: The Potato in World History, is structured in three main sections—South America, Europe, and The World—each weaving together the potato’s biological, cultural, and socio-economic significance with a narrative that is both scholarly and accessible. Reader, a writer and photojournalist with an anthropological lens, draws on the foundational work of scholars like Redcliffe N. Salaman and William H. McNeill, while infusing the text with wit and a keen eye for historical detail, making the potato’s story a lens through which to view broader emulate human development.
The first section delves into the potato’s origins in the Andes Mountains and altiplano of South America, where it was domesticated around 8,000 years ago from a poisonous plant with high alkaloid content into a nutritious tuber that became a dietary cornerstone for Andean civilizations. Reader describes how indigenous peoples cultivated thousands of potato varieties adapted to diverse altitudes, transforming a once-toxic plant into a versatile food source rich in carbohydrates, protein, vitamin C, and potassium. The book details the Spanish conquest of the region, where the potato’s ability to feed large numbers of conscripted laborers supported colonial mining operations. However, it took decades for Europeans to recognize the tuber’s value, as it initially faced suspicion and was slow to integrate into their diets. Reader intersperses modern observations of Andean potato farming, highlighting the crop’s enduring role in the region’s culture and economy.
In the second section, Reader follows the potato’s transatlantic journey to Europe, where its introduction in the 16th century marked a turning point in agricultural and demographic history. The tuber’s adaptability to various climates and soils, along with its high nutritional yield—about 75% of its biomass is edible compared to 33% for grains—made it a game-changer. Initially met with resistance and even blamed for ailments like leprosy, the potato gradually gained acceptance as a healthful staple, particularly in Ireland, where it became a dietary mainstay. Reader examines the catastrophic European Potato Failure of 1845–1850, particularly the Irish Great Famine, arguing that the disaster was not solely due to the late blight fungus but also a result of governmental policies and over-reliance on a single, vulnerable variety called the Lumper. The famine led to massive population declines and emigration, underscoring the potato’s dual role as both a sustainer and a source of tragedy when mismanaged. The section also explores how the potato fueled population booms in Europe by providing a reliable food source, contributing to the Industrial Revolution and urbanization.
The final section traces the potato’s global spread, from its adoption in places like Papua New Guinea and China—now the world’s largest potato producer and consumer—to its potential role in future space exploration, such as NASA’s plans for potato cultivation on Mars missions. Reader addresses the crop’s modern challenges, including its status as the world’s most chemically dependent crop due to persistent threats like late blight, which continues to mutate into resistant strains. He discusses efforts to preserve the potato’s genetic diversity, particularly through institutions like the International Potato Center in Peru, which safeguards thousands of varieties to ensure food security in a world increasingly reliant on the tuber. The book highlights the potato’s paradoxical nature: a nutrient-packed, efficient crop that can sustain populations through hardship, yet one that has also perpetuated poverty by enabling subsistence without necessarily fostering economic advancement.
Reader’s narrative is enriched with historical anecdotes, such as the potato’s early purchase as a Christmas treat in Seville in 1573 and the British Empire Potato Collecting Expedition of 1938, which gathered over 1,100 specimens. While the book is praised for its readable style and broad scope, some critics note its limited focus on culinary aspects and modern industrial farming, such as the rise of fast-food chains like McDonald’s that have driven potato consumption. Nonetheless, Reader’s interdisciplinary approach—blending botany, history, economics, and anthropology—paints a vivid picture of the potato as a transformative force in human civilization. Potato: A History of the Propitious Esculent ultimately reveals how this unassuming tuber has been both a blessing and a burden, shaping the course of history with its remarkable adaptability and enduring challenges.
