Steve Bisciotti is best known as the owner of the Baltimore Ravens, which he bought in the early 2000s. Although he came from a middle-class family, money became incredibly tight after his father sadly died from leukaemia when Bisciotti was just eight years old. His grandfather, who had worked as a salesman for Ford, was left to support the family and Steve worked odd jobs to pay his way through college.

After graduating, he and his cousin launched the staffing company Aerotek, working out of a basement with second-hand equipment. The business quickly grew into the Allegis Group, now a multibillion-dollar company that's earned Bisciotti a fortune of $6.9 billion (£5.4bn).
