What were the official record keepers of the sumer called?

The appropriate response is scribes. Scribes are considered to be one of the important people in the history. They were prepared to compose cuneiform and record a considerable lot of the dialects talked in Mesopotamia. Without copyists, letters would not have been composed or perused, regal landmarks would not have been cut with cuneiform, and stories would have been told and afterward overlooked.

I believe it was James Madison
