We often think of memes as living solely online. But the term “meme” was coined in the 1970s -- before the birth of the internet -- by evolutionary biologist Richard Dawkins. And, more surprisingly, the image that's often considered to "the first meme" appeared as early as the 1940s. 

A figure with a bulbous head and sausage fingers, peering over a wall, mysteriously popped up all over the globe during World War II, accompanied with three simple words: “Kilroy Was Here.” The phrase’s original meaning may come from the belly of warships, but what it came to represent bears many characteristics of a true-blue internet meme. In the first episode of our meme series, we tell the story of where "Kilroy Was Here" came from, how it spread, and what it tells us about the essence of memes.
