Peanut butter is one half of America's favorite sandwich and on March 1st, we're celebrating National Peanut Butter Lover's Day. In 1884, Montréal based chemist Marcellus Gilmore Edson patented peanut butter. In his patent, he described peanut butter as having "a consistency like that of butter, lard, or ointment" according to his patent application which described a process of milling roasted peanuts until the peanuts reached "a fluid or semi-fluid state." Ten years later, a St. Louis businessman named George Bayle began producing and selling peanut butter for hungry customers.

By 1922, chemist Joseph Rosefield came into the picture and invented modern, nonseparating peanut butter—later licensing the technology to Peter Pan. In 1932, Rosefield created Skippy peanut butter, which is still one of the most popular peanut butter brands to this day.

One of the biggest misconceptions about peanut butter comes from the name itself, as peanuts don't belong to the nut family. Instead, they grow in the ground and are legumes—just like beans, soybeans and chickpeas. Another little known fact about peanut butter is the amount of peanuts it takes to make a 12-oz jar—it's 540!

Many celebrities and public figures have been open about their love for peanut butter—from Elvis Presley to Jerry Seinfeld to President Jimmy Carter. And we know that many of our readers are peanut butter fanatics as well. In honor of all the peanut butter lovers around the world, we've curated some of our favorite peanut butter tattoos in the gallery below. Take a look at the tattoos and let us know your favorite peanut butter product on social media.
