Joan Anderson's role in introducing the hula hoop from her native Australia went unsung until the 2018 documentary Hula Girl. She reportedly settled with Wham-O

Because of a deal made on a handshake in a parking lot, she was long left out of a famous toy’s story. When she was 94, a documentary changed that.

Anderson claimed she came up with the name 'hula hoop' and played a crucial role in introducing the toy to the US.
