It was a momentous year, 1912.

The Republic of China was founded. Albert Berry made the first parachute jump from a plane. The Titanic sank. Harriet Quimby became the first woman to fly across the English Channel. And a layer of sweet white cream was sandwiched between two thin, crisp chocolate cookies. The Oreo was born.

The name Oreo, according to Nabisco, could originate from the Greek word “oreo,” meaning hill or mountain.

When tested, the cookie was originally shaped like a hill, and since Nabisco’s president had a penchant for classical names, it became Oreo.

Originally, there was a second flavor, lemon meringue, but the classic combination of chocolate and cream is the lone survivor, aside from some seasonal and regional variations.

Nabisco says more than 20 million Oreos are dunked, unscrewed, ground into cakes or pies, baked into cookies or are otherwise eaten every day, for a grand total of 7.5 billion per year.
