16. Michael and Ralf Schumacher
Sport: Auto Racing
Accomplishments: Michael: 7x world champion; Ralf: Six career wins
Michael is considered by many to be the greatest Formula-1 driver in history, having won seven world championships (including five in a row from 2000 to 2004) and 91 races overall. While Ralf's career was less illustrious than his brother's, he nevertheless managed to win six races in his 10-year career and currently drives in some sort of Formula-1 "seniors tour." The Schumachers are the only brothers in history to both win Formula-1 races, and were also the first brother combination to finish first and second in the same race (which they did five times).
