Before ALS and his ample scientific offerings, Stephen Hawking was a university student who did his fair share of cutting up. Seen above holding the white handkerchief, Hawking joined the Oxford University boat club where he served as a rather daring coxswain whose strategies would result in a number of damaged boats.
Interestingly enough, it was while rowing that Hawking exhibited some early signs of his illness. At age 21, Hawking would be diagnosed with ALS and a life expectancy of two years. Today, Hawking is 73.
