The question “who invented catsup” does not have a single, simple answer. Unlike many modern food products that can be traced to a specific inventor and date, catsup evolved over centuries across multiple continents. No one person created it. Instead, a series of innovators — from anonymous Asian fishermen to 19th-century American entrepreneurs — each contributed a crucial piece to the condiment we know today. Understanding when catsup was invented requires following this chain of innovation from ancient fermentation techniques to industrial food production.
The Anonymous Origins: Who Made the First Catsup?
If we define catsup broadly — as a fermented sauce used to enhance the flavor of food — then its inventors were the fishermen and cooks of ancient southern China and Southeast Asia. As detailed in our comprehensive guide to the history of catsup, fermented fish sauces known as kê-tsiap in the Hokkien dialect have been produced in the region for over two thousand years. These early sauce makers are the true original inventors of catsup, even though the product they created would be unrecognizable to modern consumers.
We do not know the names of these early innovators. Fermented fish sauce was a communal, traditional product, developed and refined over generations by countless unnamed cooks. The techniques were passed down orally and through practice, not recorded in cookbooks or patent applications. Who made catsup first? Anonymous communities across Southeast Asia, working with fish, salt, and time.
English Adapters: Mushroom Ketchup and Its Creators
When English traders brought the concept of kê-tsiap back to Europe in the 17th and 18th centuries, a new wave of innovation began. English cooks could not replicate the original fish sauce exactly, so they adapted it using local ingredients. The most significant adaptation was mushroom ketchup, which became a standard condiment in British kitchens by the mid-1700s.
Several cookbook authors helped popularize and refine English ketchup recipes. Eliza Smith’s The Compleat Housewife (1727) included an early English ketchup recipe. Elizabeth Raffald’s The Experienced English Housekeeper (1769) featured a mushroom ketchup recipe that became widely copied. Hannah Glasse, one of the most influential food writers of the 18th century, also published ketchup recipes in her bestselling The Art of Cookery Made Plain and Easy. These women did not invent catsup, but they played a vital role in transforming it from an exotic Asian import into a mainstream English condiment.
James Mease: The Father of Tomato Catsup
When people ask “who invented catsup” in the modern, tomato-based sense, the name most historians cite first is James Mease. A Philadelphia physician, scientist, and horticulturist, Mease published what is widely regarded as the first recipe for tomato-based ketchup in 1812. His recipe appeared in a medical and agricultural encyclopedia and called for tomato pulp, spices, and brandy.
Mease’s recipe was significant for two reasons. First, it established the tomato — still viewed with suspicion by many Americans at the time — as a legitimate ingredient for ketchup. Second, it marked the beginning of the shift away from mushroom and walnut varieties toward the tomato-based product that would eventually dominate the market. Mease referred to tomatoes as “love apples,” reflecting the romantic associations that some cultures had attached to the fruit.
It is important to note that Mease’s recipe was not identical to modern ketchup. It lacked the sugar and vinegar that characterize today’s product, and it was likely thinner and more savory. But it was the first documented step toward the tomato catsup we know today, and for that reason, Mease deserves recognition as a key figure in the answer to when was catsup invented in its tomato form.
Jonas Yerkes: The First Commercial Catsup Producer
While James Mease created the first known recipe, Jonas Yerkes is often credited as the first person to sell tomato ketchup as a commercial product. In the 1830s, Yerkes began bottling and distributing tomato ketchup to local grocers in the Philadelphia area. His product was among the first to move catsup from the home kitchen to the store shelf, establishing the commercial model that would define the industry for the next two centuries.
Yerkes’s early commercial catsup was a far cry from the standardized, quality-controlled products of today. Like many food manufacturers of the era, he faced significant challenges with preservation and consistency. Without refrigeration or modern canning techniques, early bottled catsup was susceptible to spoilage, and producers often resorted to chemical preservatives and artificial coloring to maintain the appearance and shelf life of their products.
Henry J. Heinz: The Man Who Made Catsup an American Icon
No discussion of who invented catsup — or at least who perfected it — is complete without Henry John Heinz. Born in 1844 in Pittsburgh, Pennsylvania, Heinz was a natural entrepreneur who began selling horseradish from his mother’s garden as a young man. In 1876, he introduced his tomato ketchup, and within a few decades, it had become the best-selling condiment in America.
Heinz’s contribution was not the invention of a new recipe but the transformation of an existing product through quality, marketing, and scale. At a time when most commercial ketchup was made from unripe tomatoes, artificial preservatives, coal tar dyes, and questionable fillers, Heinz committed to using only ripe, fresh tomatoes. He increased the vinegar content of his recipe, which acted as a natural preservative and allowed him to eliminate sodium benzoate and other chemical additives.
This commitment to purity was not just ethical — it was brilliant marketing. Heinz became one of the most vocal supporters of the Pure Food and Drug Act of 1906, which established federal oversight of food safety for the first time. By championing food purity, Heinz positioned his brand as the trustworthy choice in a market plagued by adulteration scandals. His iconic clear glass bottle — a rarity in an era when most condiments were sold in opaque containers — was a deliberate signal of transparency: if you had nothing to hide, you let consumers see what they were buying.
Heinz also played a role in the spelling shift from catsup to ketchup, as his brand’s dominance helped establish “ketchup” as the standard American spelling. And his aggressive expansion — into international markets, into new product lines, and into the emerging world of mass advertising — turned a regional condiment into a global phenomenon.
Other Notable Contributors
Beyond these central figures, several other individuals and groups contributed to the development of catsup as we know it. Dr. John Cook Bennett, the Ohio physician who championed the tomato as a health food in the 1830s, helped overcome public fear of the fruit and indirectly boosted demand for tomato-based products including catsup. For the full story of this fascinating episode, see our article on catsup as medicine.
Harvey Washington Wiley, the chief chemist of the USDA and a driving force behind the Pure Food and Drug Act, also deserves mention. While Wiley did not make catsup, his regulatory efforts forced manufacturers to clean up their products, which ultimately benefited quality-focused producers like Heinz and raised the overall standard of commercial ketchup.
In the 20th century, food scientists at major corporations continued to refine the catsup recipe, optimizing sugar-to-vinegar ratios, developing more efficient processing methods, and creating the thick, smooth consistency that modern consumers expect. These anonymous corporate scientists are the latest link in a chain of innovation that stretches back thousands of years.

- 1830s: Jonas Yerkes begins selling tomato ketchup commercially. Dr. John Cook Bennett promotes tomato extract as medicine.
- 1876: Henry J. Heinz introduces his tomato ketchup, which will become the industry standard.
- 1906: The Pure Food and Drug Act helps clean up the commercial ketchup industry.
- 1988: The USDA standardizes the spelling as “ketchup” and establishes official ingredient standards.
The Collective Invention of Catsup
Ultimately, who made catsup is a question best answered in the plural. Catsup was not invented by one person in one place at one time. It was collectively developed over centuries by fishermen in Southeast Asia, traders on merchant ships, cookbook authors in English country houses, experimenters in American kitchens, and industrialists in Pittsburgh factories. Each generation took what it inherited, adapted it to new tastes and technologies, and passed it along.
This collective, evolutionary origin is part of what makes the history of catsup so compelling. It is a story not of a single eureka moment but of slow, cumulative innovation across cultures and centuries — the kind of story that reminds us how interconnected the world’s culinary traditions truly are.
