"Genius is one per cent inspiration, ninety-nine per cent perspiration."
These are the words of famous 19th-century American inventor Thomas Edison, who you may not know had a hearing impairment. There have been plenty of significant figures with disabilities or health conditions throughout history - but you may not have learnt about them at school.
Want to learn more about some of them? Take our BBC Bitesize quiz. It covers those you may have heard of, like Louis Braille and Helen Keller, to less well-known individuals, like a suffragette who used a wheelchair and a Second World War spy with an artificial limb.
Good luck!
