From a young age, Stephen Hawking had a strong sense of wonder and was full of questions about the world around him and the stars above. He would spend his whole life trying to figure out how the universe worked, including discovering truths about black holes and energy. And when he was diagnosed with a rare disease called ALS that destroys the nerve cells in the body, he would find his own mental energy to carry on with his studies even after his limbs and vocal chords stopped working. He became one of history's most influential scientists.
