University of Sheffield

Perhaps the best known of the five Nobel laureates from this 105-year-old university, one of the six original "redbricks", is Howard Florey, the co-developer of penicillin. Professor emeritus David Hughes has lent his name to what was previously known as Asteroid 4207. The university teaches 25,000 students, including around 3,900 from 120 countries, and employs about 6,000 staff.
