JD Salinger was an American author best known for his 1951 novel The Catcher in the Rye. He grew up in New York to immigrant parents and attended a military academy as a teenager. During World War II, he served in the army and took part in the Normandy invasion. After the war, he struggled with PTSD and married briefly before focusing on writing. The Catcher in the Rye was hugely successful but also controversial, and Salinger became a reclusive writer, guarding his privacy intensely. He lived quietly in New Hampshire until his death in 2010 at age 91.
