The brothers started to pull together tales from villagers and peasants in the early 1800s and soon found themselves with hundreds of old wives tales and stories.
In 1812, the Brothers Grimm published their first collection of fairy tales, 'Children's and Household Tales', which contained around 200 dark and, at times, chilling stories.
Between 1816 and 1818 the Brothers Grimm published a further two volumes of German legends and an early literary history.
In the last 100 years, numerous Grimm fairy tales have been adapted for film and television, from Disney classics to much darker modern interpretations.
Little Red Riding Hood, Cinderella, The Frog Prince, Hansel and Gretel, Rapunzel, Rumpelstiltskin, Sleeping Beauty and Snow White have all become children's favourites despite their sinister origins.
As well as writing their famous tales, the Grimm Brothers also started to compile the first German dictionary.
Wilhelm died on 16th December 1859 having completed D. Jacob completed A, B, C and E before dying at his desk working on F, and the actual word he was on was fruit.
