Christopher Clive Langton Gregory
(The first Director of the University of London Observatory).

Christopher Clive Langton Gregory was born around 1890 in Dorset. His father, married to Octavia, was a clergyman and Christopher spent the early years of his life at the family home of "Melville", a large Victorian house in Parkstone, near Poole in Dorset. He spent his childhood collecting fossils, creating telescopes, and holding conversation with Alfred Russel Wallace, the co-discoverer with Charles Darwin of Natural Selection. 

Gregory's education at Cambridge University (reading physics) was put on hold due to the First World War, during which he served in France, and in particular The Battle of the Somme. Towards the end of 1918, Gregory was sent to Salisbury Plain to carry out scientific work in sound ranging, a method of detecting enemy guns / armament for the Government. Gregory's astronomic career commenced when he was appointed the First Assistant of the National Observatory of Egypt, a post he held for two years. His responsibilities included observing the moon, and to alert the King upon the sighting of a New Moon, thus heralding the start of Ramadan. 

Gregory married Helen Patricia Gibson and on 24th July 1923 their son Richard was born. In 1928, a new Observatory was begun in the grounds of Mill Hill park, London, the lease being arranged with Hendon Urban District Council for a period of 999 years. The Observatory was formally opened the following  year, and was further expanded during 1937 -38. Gregory was appointed the first Director of Astronomy, University of London Observatory
