One of the earliest recorded appearances of manufactured sex dolls dates to 1908, in Iwan Bloch's "The Sexual Life of Our Time". Bloch wrote:
In this connection we may refer to fornicatory acts effected with artificial imitations of the human body, or of individual parts of that body.

Iwan Bloch (also known as Ivan Bloch) (April 8, 1872 – November 21, 1922) was a German dermatologist. Together with Magnus Hirschfeld and Albert Eulenburg, Bloch proposed the new concept of a science of sexuality: Sexualwissenschaft or sexology.
