My guess goes for Shirley Temple. I recall that she has come out and made accusations, but I don’t know if she was the first to say something. She certainly was among the first child actors in Hollywood. According to IMDb, her first film, Kid’s Last Stand, was released in 1932 when she was three. The first “talking picture” was released in 1927: The Jazz Singer with Al Jolson, so Shirley Temple’s first movie was released only five years later. In Shirley Temple’s book Child Star (October 1, 1988), she reported molestation that occurred during a casting call for The Wizard of Oz, but it appears that she was sexualized much earlier than that. Shirley Temple was featured in a series of films called Baby Burlesks. These films were distinctly suggestive in content. The first of these films was released in 1932 when Shirley Temple was three years old, but she may have been as young as two when they were actually filmed.
