I was amazed to read the obituary of Sir Anthony Epstein who died at the age of 102 last week.

He suspected that a lymphoma (cancer) named after Dennis Burkitt (who first described it) was caused by a virus and was determined to discover that virus. He received numerous specimens regularly flown in from Uganda and consistently failed to find any evidence until a flight was seriously delayed and the specimens when they finally arrived all looked cloudy.
