Not saying he did. However, to say that the Uncle Remus Tales are of African/African American history/literature is unfair, in my opinion. Yes, the stories are appropriated and “stolen,” but if you’ve read some of the stories, especially ones with Uncle Remus, they do not appear as having being written by an African American (they weren’t) and very much come off as appeasement to white Americans who were reading about an African American character. If one has read enough 19th century literature by African Americans, they would assume that no self-respecting African American writer would have created such a character as Remus.
Yes, the Brers originate from African/African American folklore, but SotS is not necessarily based on the original tales as they are before appropriation. It’s not like Walt Disney consulted African folklorists. The movie is based on version a white author wrote, versions that were read to many white children that included a fictional black character that white people loved (for obvious reasons).
