In July 1971, the New York Times published an article about a Greek teenager from the Washington Heights neighborhood named Demetrios. He worked as a delivery courier and used the few minutes between drop-offs to write his name on walls, subway stations, and train cars. His signature was everywhere: TAKI 183. “TAKI” came from his Greek nickname, and “183” was the street where he lived. The Times article turned a neighborhood kid into the first globally known graffiti writer.

After him came hundreds, then thousands. The rules were simple: choose a name, paint it everywhere, and be recognized by your style. Subway cars became moving galleries, traveling through every part of the city. Trains moved — and your art moved with them. It became one of the first forms of “social network” communication in physical space, decades before the internet.

Graffiti emerged alongside hip-hop in the same neighborhoods, at the same time, for the same reasons. Young people in the Bronx and Harlem had no access to galleries, record labels, or official platforms. So they built their own: walls for visual art, turntables for music, streets for dance. Four forms of expression that required no permission from anyone.

Over time, graffiti evolved from street tagging into a global visual language. Artists like Banksy brought it into galleries and auctions, where works now sell for millions. But at its origin, graffiti was something much simpler — and more defiant.

It was the act of a kid writing their name on a city that ignored them, and forcing that city to notice.
