One of the earliest versions to incorporate the wicked stepmother, stepsisters, slipper and hunt by the king for the owner of the slipper was written in 1634 by Giambattista Basile, an Italian. But it was Charles Perrault who introduced the elements of the fairy godmother, the pumpkin and the glass slipper in 1697.
I found the Perrault version of this tale on a new-to-me site called SurLaLune Fairy Tales. This is the version that Disney adapted, although they did include the birds that help Cinderella in the German version. Of course they did; they're Disney and there always have to be helpful animals. Except that, not surprisingly, the animals in the Brothers Grimm tale do not talk and sing. In Perrault's hands, the stepsisters are ugly and Cinderella's father was a doormat for her stepmother and allowed his daughter to be treated like a servant. No wonder she was so eager to rush off and marry a man she hardly knew who seemed to only love her for her looks.
