The much-admired ophthalmologist Dr Dennis Williams died earlier this year. Dr Williams was born in Nigeria but educated in Sierra Leone, and was the only ophthalmologist to remain in the country during the war. He worked for Sightsavers for much of his life, and was appointed Vice President of Sightsavers on his retirement in 2008; the only staff member ever to receive this honour. He will be remembered for this courage, his leadership, his humour, and his humility. Dr Williams, who was suffering from cancer, is survived by his wife, Pamela, and four children.
