How did peanut butter get its name?

Peanut butter was not always known by that name; in fact, it had several different names before the one we use today. When it was first introduced in the late 1800s, it was called "peanut paste" or "peanut butter paste". In 1895, a man named John Harvey Kellogg developed a product that he called "peanut butter", but he was not the first person to use the name. In 1903, another man named George Bayle Jr. patented a process for making peanut butter, and he is often credited with popularizing the name.
