I am doing homework for a newspaper report about Neil Armstrong and i need a word that means "someone who makes history" or "marking a time in history". Please answer so I get a good grade, really confused right now.
You might consider using a word history-maker (history maker)
A person who influences the course of history or does something spectacular or worthy of remembrance.
Definition is from here.
The greatest history makers in our time are not politicians and statesmen, but inventors, entrepreneurs, and others who are transforming the technological base of civilization and whose search for new markets is leading us into a more global economy.
Example is from here.
As suggested, Archetype:
1 : the original pattern or model of which all things of the same type are representations or copies : prototype
- … the House of Commons, the archetype of all the representative assemblies which now meet … —Thomas Babington Macaulay
; also : a perfect example
- He is the archetype of a successful businessman.
