The Scarecrow first appeared in the 1941 issue of Worlds Finest #3 - Riddle of the Human Scarecrow. As a child, young Jonathan Crane found joy in scaring birds, a habit he never quite grew out of. Later in life he became a professor of psychology at the Gotham University,
but his methods were more than just unorthodox, and included experimenting on his own students. Crane was mocked by his fellow professors because his lanky features and shabby clothes that made him resemble a Scarecrow. After he learning about this ridicule, he decided to spread fear in exchange for money. (and more books) Thus, the Scarecrow was born–a symbol of both poverty and fear.
