I am sure that colleagues will be saddened to hear of the death of Chris Clarke who passed away on 16th April. Chris gained his PhD in General Relativity from the University of Cambridge as part of the group led by Dennis Sciama. After positions at Hamburg and York, Chris moved to Southampton in 1986 to take up the Chair in Applied Mathematics and lead the GR group.
He was best known for his work on singularities summarised in his book “The analysis of space-time singularities”. However his work was wide ranging and also covered topics in astrophysics, numerical relativity, the philosophy of quantum theory and the physics of the brain. He left the University of Southampton in 1999 to work free-lance and devote more time to support for environmental and spiritual causes but continued to publish scientific papers on relativity and quantum theory.
