Leonhard Fredrik Rääf (1786–1872) also known as Ydredrotten was a Swedish folklorist, local historian and conservative politician from Ydre.[1] [2] During a time Rääf had a literary salon in Tomestorp which was frequented by among others Per Daniel Amadeus Atterbom.[1] In 1843 Rääf moved to a farm in Forsnäs where he lived until his death in 1872.
Rääf is buried together with some possessions in a Viking-style mound at the shores of Lägern.[1]
