GELATIN

                                     Before this century, the glue needed for gelatin had to be laboriously extracted from meat bones. In the Middle Ages, cleer antiers were a popular source of the glue';later, calves' feet and knuckles. Housewives in the 19th century used isinglass, made from the membranes of fish bladders.

                                   Then, in 1890, a Jamestown, New York man named Charies B. Knox was watching his wife make calves'-foot jelly when he decided that a per-packaged easy-to-use gelatin mix was just what the housewife needed. Knox set out to develop, manufacture and distribute the granulated gelatin, while his wife invented recipes for the new kitchen staple. Now everyone could make gelatin in one minute instead of hours.
