Peanut butter's invention traces back centuries , with ancient roots and key modern developments in the late 19th century.

Ancient Origins

The earliest known peanut butter-like paste dates to ancient South American Incas around 3,500 years ago, who ground peanuts into a spread. This predates European contact, showing peanuts' long history in the Americas as a nutrient- rich food.

Modern U.S. Breakthroughs

In 1884, Canadian Marcellus Gilmore Edson patented peanut paste made by milling roasted peanuts between heated surfaces.

Dr. John Harvey Kellogg, famous for cereals, patented a process in 1895 for boiling and grinding raw peanuts into a digestible paste for patients with chewing issues at his Battle Creek Sanitarium.

In 1903, Dr. Ambrose Straub of St. Louis patented a peanut butter-making machine.

Popularization and Myths

Peanut butter debuted to the public at the 1904 St. Louis World’s Fair , sparking its rise as a commercial hit.

A common myth credits George Washington Carver, but he promoted peanuts broadly without inventing the spread—despite his agricultural innovations.

Cultural Impact

From a health food for the elderly, peanut butter evolved into a pantry staple by the early 1900s, now in 95% of U.S. homes for PB&J, desserts, and more. Imagine its journey: from Inca hands to Kellogg's lab, then lunchboxes everywhere—proving simple ingredients spark global obsessions.

TL;DR: Modern peanut butter emerged in 1895 via Dr. John Harvey Kellogg, building on ancient Inca practices and prior patents; first sold widely in 1904.
