Inventors/Inventions

The original quote I'm working from is "Necessity is the mother of invention" So maybe I should look at inventors/inventions and maybe how I could incorporate these into the poster(s)

Einstein is obviously a global and historical icon and instantly recognisable. I think he would work well "necessity is the mother of invention", I'm not sure he would work with "Difficult situations inspire ingenious solutions" as it doesn't involve the word 'invent'. Maybe that's just me though
