I spent some of my time today looking into the life and starting of Erté and how he came to do what he did. There essentially wasn't much in terms of information more so that was given on Wikipedia as I did not want to use facts for them as they cannot always be accurate. However all the information I found after searching a little bit deeper lead me to the same conclusion. I summarized important aspects into a who's who power-point.
