Who invented the type of script used in autographs?
Cuneiform script Cuneiform script ( or or ), one of the earliest systems of writing, was invented by the Sumerians. It is distinguished by its wedge-shaped marks on clay tablets, made by means of a blunt reed for a stylus. The name "cuneiform" itself simply means "wedge shaped".
Yelü Diela Yelü Diela (耶律迭剌), younger brother of Khitan Emperor Yelü Abaoji, invented the "Khitan small script" to accommodate the more agglutinative Khitan language about 925 — based partly on the earlier "Khitan large script" or Chinese-like logographic writing, but also after having been inspired by the vertically written Old Uyghur alphabet that was shown to him by an ambassador.
