Mark Zuckerberg, 23, founded Facebook while studying psychology at Harvard University. A keen computer programmer, Mr Zuckerberg had already developed a number of social-networking websites forfellow students, including Coursematch, which allowed users to view people taking their degree, and Facemash, where you could rate people's attractiveness.
