The Scarecrow is a supervillain appearing in American comic books published by DC Comics. Created by writer Bill Finger and artist Bob Kane, the character first appeared in World's Finest Comics #3 (September 1941). He has since become one of the superhero Batman's most enduring enemies belonging to the collective of adversaries that make up his rogues gallery. In the DC Universe, the Scarecrow is the alias of Jonathan Crane, a professor of psychology turned criminal mastermind. Abused and bullied in his youth, he becomes obsessed with fear and develops a hallucinogenic drug—dubbed "fear toxin"—to terrorize Gotham City and exploit the phobias of its protector, Batman. As the self-proclaimed "Master of Fear", the Scarecrow's crimes do not stem from a common desire for wealth or power, but from a sadistic pleasure in subjecting others to his experiments on the manipulation of fear. An outfit symbolic of his namesake with a stitched burlap mask serves as the Scarecrow's visual motif. The character has been adapted in various media incarnations, having been portrayed in film by Cillian Murphy in The Dark Knight Trilogy, and in television by Charlie Tahan and David W. Thompson in the Fox series Gotham, and Vincent Kartheiser in the HBO Max streaming series Titans. Henry Polic II, Jeffrey Combs, Dino Andrade, John Noble, and Robert Englund, among others, have provided the Scarecrow's voice in animation and video games. (via Wikipedia)
Born in Georgia, Jonathan Crane is abused by his great-grandmother, and is bullied at school for his resemblance to Ichabod Crane from Washington Irving's "The Legend of Sleepy Hollow", sparking his lifelong obsession with fear and using it as a weapon against others. In his senior year, Crane is humiliated by school bully Bo Griggs and rejected by cheerleader Sherry Squires. He takes revenge during the senior prom by donning his trademark scarecrow costume and brandishing a gun in the school parking lot; in the ensuing chaos, Griggs gets into a car accident, paralyzing himself and killing Squires. Crane's obsession with fear leads him to become a psychologist, taking a position at Arkham Asylum and performing fear-inducing experiments on his patients. He is also a professor of psychology at Gotham University, specializing in the study of phobias. He loses his job after he fires a gun inside a packed classroom, accidentally wounding a student; he takes revenge by killing the professors responsible for his termination and becomes a career criminal. As a college professor, Crane mentors a young Thomas Elliot. The character also has a cameo in Sandman (vol. 2) #5. In stories by Jeph Loeb and Tim Sale, the Scarecrow is depicted as one of the more deranged criminals in Batman's rogues gallery, with a habit of speaking in nursery rhymes. These stories further revise his history, explaining that he was raised by his abusive, fanatically religious great-grandfather, whom he murdered as a teenager.(via Wikipedia)
