The firefighting system of the Van der Heyden brothers in 17th century Amsterdam
In 17th-century Amsterdam, facing rampant fires in its booming economy, painter and system-thinker Jan van der Heyden revolutionized urban firefighting by inventing flexible hoses and a continuous-pressure pumping system. This innovative technology, coupled with a meticulously designed civic system of alarms and incentives, dramatically reduced fire damage, an early example of 'systems analysis'. Hacker News appreciated the deep dive into historical ingenuity and systems design, sparking debate on the definition of 'invention' in firefighting.
The Lowdown
Seventeenth-century Amsterdam, the wealthiest city globally, also faced a significant peril: widespread fires fueled by its material abundance and burgeoning industries. Despite early attempts at organized firefighting with existing pump engines, these proved inadequate against large conflagrations, often failing to reach the source of the blaze and resulting in immense losses for individuals and the city.
- Early 17th-century Amsterdam experienced devastating fires, exacerbated by highly combustible materials in homes and industries like sugar refining and printing.
- Existing German-made Hautsch fire engines, though numerous, were limited by rigid nozzles and intermittent water flow, rendering them ineffective for large or high fires.
- Jan van der Heyden, a celebrated painter, first distinguished himself by designing and implementing a highly effective street lighting system for Amsterdam.
- He and his brother Nicolaas then invented a new fire engine featuring flexible leather suction hoses for continuous water supply, long 'snake' hoses for precise targeting inside buildings, and an air chamber for sustained, high-pressure water streams.
- A crucial fire at military stores demonstrated the new engine's superior capability, paving the way for its city-wide adoption.
- Van der Heyden oversaw the full implementation, including manufacturing lightweight engines, establishing a comprehensive alarm system with trumpeters and lamplighters, and creating market incentives for rapid response from fire companies.
- This holistic, 'systems analysis' approach, combining technological innovation with organizational reform, drastically reduced fire losses in Amsterdam.
Van der Heyden's pioneering work showcased that true progress wasn't just about a single invention, but about designing an entire system around it to maximize its effectiveness, transforming civic safety in one of the world's leading cities.
The Gossip
The 'Invention' Indignation
Many commenters took issue with the article's claim that Amsterdam 'invented the fire department,' pointing to earlier forms of organized firefighting. Roman examples, such as the Vigiles Urbani and the notorious private fire brigade of Marcus Licinius Crassus, were frequently cited. The discussion often centered on defining 'fire department'—whether it referred to the general concept of organized fire suppression or the specific technological and systemic innovations introduced by the Van der Heydens. The HN moderator even intervened to adjust the title, acknowledging the semantic debate.
Crassus's Controversial Crews
A notable tangent in the comments explored the infamous Roman figure Marcus Licinius Crassus, who leveraged fires for personal gain. His private fire brigade would allegedly refuse to extinguish burning properties until the distressed owner sold them to Crassus at a drastically reduced price. This historical anecdote provided a stark contrast to the civic-minded innovations discussed in the article, highlighting a very different, profit-driven approach to urban emergencies.
Linguistic Links & Local Lore
Commenters shared interesting observations related to language and cultural context. One user inquired about the etymology of the Dutch word 'slang' (meaning 'snake' and used for the fire hose) and its potential link to the English word. Another Dutch commenter expressed humorous surprise that the well-known painter Van der Heyden was also an engineer, noting how the story perfectly encapsulates a 'Dutch Golden Age' stereotype of polymathic ingenuity.
