The Unusual Life of Jack Black: Queen Victoria’s Rat Catcher
On a grey day in London in 1851, a crowd gathered around a makeshift stage to witness an unusual spectacle. At the center stood Jack Black, a showman clad in a top hat and leather sash, surrounded by a swarm of rats. He claimed to be Queen Victoria’s authorized rat catcher and amazed the audience with his ability to capture hundreds of vermin using only his hands while promoting his poisons.
A Long History of Humans and Rats
This moment was just one instance in the long, intertwined history of humans and rats. The two most common species, brown and black rats, originated in Asia between 1 to 3 million years ago. They survived the last ice age and gradually adapted to human environments. Their omnipresence even secured them a place in the Chinese zodiac, symbolizing new beginnings. As generalists, they adapted to diverse climates and diets, making them perfect stowaways on trade routes between East Asia and the West.Black rats were the first to travel abroad, hitching rides on ships from India to Egypt around 5,000 years ago. Some believe their arrival in Egypt contributed to the ancient reverence for cats, natural rat hunters. Trade with the Romans brought black rats to Europe, and by 300 CE, they had spread as far as the Anglo-Celtic Isles. These rodents gained notoriety not just for their rapid reproduction but also for spreading diseases through their droppings and urine. In the late 1340s, the Black Death ravaged Europe, killing millions and solidifying the rat’s infamy.
Misplaced Blame: The Truth About Plague
However, the blame placed on rats is somewhat misplaced. Black rats do not directly spread plague to humans; rather, they carry fleas that transmit the disease. Brown rats, which had not yet reached Europe at that time, were not involved in the pandemic.Meanwhile, in Japan, brown rats were being domesticated as pets, with guidebooks from 250 years ago offering advice on breeding affectionate rats in various colors and patterns. Brown rats eventually arrived in Europe between the 13th and 18th centuries, possibly swimming across the Volga River after an earthquake in 1727. Their larger size and adaptability allowed them to outcompete black rats, taking over homes and cities across Europe and North America.
The Rise of Brown Rats
The Industrial Revolution provided even more opportunities for brown rats to thrive, as expanding cities offered ample food and shelter. They evolved resistance to poisons, frustrating exterminators carrying on Jack Black’s legacy. A significant turning point in the human-rat relationship occurred in 1906 when the Wistar Institute in Philadelphia bred the first standardized rat strain for scientific research.Rats proved invaluable in laboratories due to their physiological similarities to humans and their intelligence, making them essential for neuroscience and psychology research. In the 1960s, scientists discovered that rats raised in enriched environments with toys and companions developed thicker brain tissue, helping establish the concept of neuroplasticity—how environment and experience shape the brain.
Rats Today: Invasive Species or Companions?
Today, rats are considered one of the world’s most successful invasive species, though they remain dependent on human priorities. In cities like New York, they are regarded as pests, prompting expensive extermination efforts. Despite these efforts, history suggests that no amount of money or expertise will ever fully eliminate our rodent companions.
Conclusion
Jack Black's life as a rat catcher reflects a unique chapter in human history—a blend of spectacle, survival, and adaptation. As we continue to coexist with these resilient creatures, understanding our shared history can help us navigate our relationship with them more thoughtfully.
