Keith Haring (Reading, Pennsylvania, 1958 – New York, New York, 1990) built one of the most immediately legible visual languages of the twentieth century out of a conviction that art belonged in public space, not behind gallery walls: a vocabulary of continuous, unbroken outline that strips figures down to pure sign, letting a body read as animated, collective, or endangered from across a subway platform.

Encouraged to draw by his father, an amateur cartoonist, Haring studied commercial art briefly before enrolling at New York's School of Visual Arts, where he gravitated to the city's downtown street art scene. Beginning in 1980, he drew directly onto the blank black paper covering expired advertisements in subway stations, working in white chalk at a pace that let him complete dozens of drawings a day; he called the subway his "laboratory," reaching a public that would never set foot in a museum, and was arrested more than once for the work.
