Sir Ken Murray, the late scientist who helped develop the first vaccine against the hepatitis B virus (HBV), has posthumously left £30 million (nearly $50 million) to a charity he founded at Edinburgh University, the Daily Record reports. The 82-year-old professor died in 2013. Murray worked at the university for more than 30 years and was one of its first researchers in genetic engineering. His will reveals his estate was worth nearly £45 million at the time of his death, a fortune mostly built on royalties from the vaccine. His donation will help support the education of young scientists and fund research and facilities at the university, where he donated about £60 million (nearly $100 million) throughout his lifetime.
