Who is the founder of founder word?

Answer 1

The short answer to this is 'nobody', but the longer answer requires a little . . . history.

Currently, the word history is defined as the study of the past (as related to the recorded events of humans; anything predating written word is 'prehistory'). The word comes from the Greek ἱστορία (historia) meaning inquiry (gaining knowledge from investigation). In this way, until around the 1930's, the word history was used to mean inquiry and was not used in its modern sense (meaning pre-1930's, any title that included the word history meant it in the Greek sense, such as 'Natural History' meant inquiry into the natural and was not an actual record of historical events). During the 1930's, the word entered the English language officially and adopted its modern sense even before its transference to our language---where it meant 'story'(Middle English) or 'record of events' and it entered the modern English language with that meaning. In Germanic and Romance languages, story and history are still synonymous. The word Historian, as a title, dates back to the 1400's, for reference to one who researches the past.

Nobody in particular is responsible for its existence, only the natural course of language evolution.
