The Brothers Grimm, otherwise known as Jacob Grimm and Wilhelm Grimm, were German librarians who also specialized in philology, which is the study of language in historical texts. During the early 19th century, they became interested in cultural research and began to collect and publish local folklore.
The Brothers Grimm wrote/archived the original fairy tales. Many of the stories that the Brothers Grimm had been passed down for generations already, so it's unlikely the stories they heard were the originals..Perrault, by the way, published his fairy tales over a century before the Brothers Grimm did. Perrault's book Tales of Mother Goose was published in 1697; Grimm's Fairy Tales was published in 1812.). The only fairy tale Disney expressly based on a Brothers Grimm story was Snow White.
