How was the first modern day crane built?

I dont want to know how they are built know cause I know they are assembled by other cranes. How was the FIRST crane built if there was not another one to help build it?

    good question, i was wondering this myself. maybe the engineers went up ladders and buildings to oversee the plan and lay it right from there.
