The History of Jelly Babies.
"Jelly Babies" are known, at least since advertisements by Riches Confectionery Company of 22 Duke Street, London Bridge in 1885, along with a variety of other baby sweets, including "Tiny Totties" and "Sloper’s Babies". But the pricing of these, at one farthing each, suggests that they were very much larger than the modern Jelly Baby.
The sweets were invented in 1864 by an Austrian immigrant working at Fryers of Lancashire, and were originally marketed as "Unclaimed Babies." By 1918 they were produced by Bassett's in Sheffield as "Peace Babies," to mark the end of World War I. Bassett's themselves have supported the "Peace Babies" name. Production was suspended during World War II due to wartime shortages.
The product was relaunched as "Jelly Babies" in 1953.
