It has been claimed that jelly beans were first mentioned during 1861, when Boston confectioner William Schrafft urged people to send his jelly beans to soldiers during the American Civil War. It was not until July 5, 1905, that jelly beans were mentioned in the Chicago Daily News. The advertisement publicized bulk jelly beans sold by volume for nine cents per pound, according to the book The Century in Food: America's Fads and Favorites. Most historians contend that jelly beans were first associated with celebrations of Easter in the United States sometime during the 1930s due to their egg-like shape. With the invention of plastic Easter eggs, jelly beans could go inside.
