Who discoverd ketchup?

Ketchup, as we know it today, evolved from various tomato-based sauces, but its origins can be traced back to the 17th century in Southeast Asia, where a fermented fish sauce called "kecap" was used. British colonists brought this sauce back to Europe, where it inspired the development of tomato ketchup in the early 19th century. The first commercial version of tomato ketchup was created by Heinz in the late 1800s, which popularized it in the United States.
