Sergio Aragonés Domenech (born September 6, 1937) is a Spanish/Mexican cartoonist and writer best known for his contributions to Mad Magazine and creator of the comic book Groo the Wanderer.
Among his peers and fans, Aragonés is widely regarded as "the world's fastest cartoonist." The Comics Journal has described Aragonés as "one of the most prolific and brilliant cartoonists of his generation."Mad editor Al Feldstein said, "He could have drawn the whole magazine if we'd let him."
Born in Sant Mateu, Castellón, Spain, Aragonés emigrated with his family to France, due to the Spanish Civil War, before settling in Mexico at age 6. Aragonés had a passion for art since early childhood. As one anecdote goes, Aragonés was once left alone in a room by his parents with a box of crayons. His parents returned sometime later to find that he had covered the wall in hundreds upon hundreds of drawings. Aragonés recalled his early difficulties in Mexico, saying, "I didn't have too many friends because I had just arrived. You're the new kid, and you have an accent. I've always had an accent... When the other kids make fun of you, you don't want to get out of the house. So you stay at home, and what do you do? You take pencils and start drawing."
