Vaseline's Inventor Ate a Spoonful Every Single Morning

Robert Augustus Chesebrough wasn't just confident in his product—he was willing to literally eat it to prove it. The English-born chemist who invented Vaseline petroleum jelly in 1859 consumed more than a teaspoon of the stuff every single day, a habit he maintained throughout his extraordinarily long life.

In a letter to the Spring Lake Gazette written just six months before his death in 1933, the 96-year-old Chesebrough explicitly credited his longevity to his daily Vaseline consumption. "I attribute my long life to eating more than a teaspoon daily of Vaseline," he wrote, making one of the strangest health claims in industrial history.

The Ultimate Product Demonstration

Chesebrough's faith in petroleum jelly bordered on the theatrical. He would stage live demonstrations where he'd burn his own skin with acid or open flames, then slather Vaseline on the fresh wounds while showing off scars from previous injuries that had supposedly healed thanks to his miracle product.

This wasn't just showmanship—Chesebrough had discovered petroleum jelly while visiting the oil fields of Titusville, Pennsylvania in 1859. Workers had been using the waxy residue that gunked up drilling equipment to heal cuts and burns. Intrigued, he brought samples back to Brooklyn and spent years refining the substance into the clear, odorless jelly we know today.

A Daily Dose of Confidence

While Vaseline is technically non-toxic and FDA-certified as safe for human consumption, modern medical professionals definitely don't recommend eating it. It's meant for topical use—lubricating skin, protecting minor cuts, preventing chapping.

But Chesebrough didn't just eat it occasionally. This was a daily ritual, a breakfast routine as regular as coffee or orange juice. Every morning, without fail, a spoonful of petroleum jelly. And he lived to 96 in an era when the average life expectancy was around 60.

Correlation or Causation?

Did the Vaseline actually contribute to his longevity? Almost certainly not. But Chesebrough's unwavering belief in his product—and his willingness to put his body where his marketing was—helped build one of the most enduring brands in American history. The Chesebrough Manufacturing Company thrived, and Vaseline remains a household staple nearly 170 years later.

So while we can't recommend adding petroleum jelly to your morning smoothie, we can admire the absolute conviction of a man who literally ate his own product every day for decades. That's commitment to the brand.
