DEREK PRIME was born and brought up in London, where he received his secondary education at Westminster City School. National Service immediately followed for eighteen months, during which time he was attached as an army teacher to the Royal Scots Greys in Germany. Upon demobilisation he went to Emmanuel College, Cambridge, where he studied history and then theology. For the next three years he taught at a London Grammar School, prior to his ordination to become pastor of Lansdowne Evangelical Free Church in West Norwood in south London. After twelve years at Lansdowne he was called to Charlotte Chapel in Edinburgh where he was pastor for eighteen years. He then devoted himself to writing and an itinerant ministry. During this time, sadly, within a few years of one another, both his younger daughter and his wife died of cancer. However, he was greatly blessed in having his other daughter and older son in Edinburgh and second son in London, giving him the joy of eight grandchildren and eight great-grandchildren, an ever-growing family!
