Oh they were the brothers Wilhelm and Jacob Grimm.  They were German, and they published folklore, back in the 19th century.  They also collected that folklore. Wilhelm and Jacob were philologists, lexicographers, academics, cultural researchers, as well as being authors!
Those books are awesome!  Jacob and Wilhelm Grimm were so talented!  I also like the tv show called Grimm that was based on their stories!
I used to love being read fairy tales when I was a child. What's your favorite fairy tale? Really?  Did you know that while fairy tales are not true, they are also not possible to be true? Hey that's neat.  What common features do fairy tales have? Well they usually have enchantments and magic!   And they feature fantasy characters, like dragons, fairies, unicorns and witches. Oh okay...and can you tell me anything about the Brothers Grimm?  Who were they?
The Brothers Grimm (' or '), Jacob and Wilhelm Grimm, were German academics, philologists, cultural researchers, lexicographers and authors who together collected and published folklore during the 19th century.
