Coulsdon (/ˈkuːlzdən/, traditionally pronounced 'Colesdon') is a town on the southernmost boundary of the London Borough of Croydon. It is surrounded by the Metropolitan Green Belt of the Farthing Down, Coulsdon Common and Kenley Common. The modern area designated Coulsdon comprises Old Coulsdon, which was the older and first settlement, and Smitham Bottom, which grew substantially with the coming of the railways.

Coulsdon is a small suburban district in South London, England. It has a strong and vibrant local history, which includes Saxon burial mounds and an Iron Age Field System on Farthing Downs, an ancient church recorded in the Domesday book, Marlpit, a former industrial chalk quarry, and the former Cane Hill Mental Hospital (a site currently under development). Appearing in the Domesday Book as Colesdone it boasted one church and rendered £7 to Chertsey Abbey. Its only other Domesday assets were 3½ hide, 7 ploughs, and woodland worth 3 hogs.

Brian Jacks (born 5 October 1946) is a British judoka who won Britain's first medal at a world championship, taking a bronze in Salt Lake City in 1967, and gained a second bronze at the 1972 Munich Olympics.

Brian Jacks later achieved national fame for his outstanding performances on the BBC programme Superstars. in which he was one of the most successful competitors. Jacks dominated the British and European version of the contest from 1979 to 1980, winning four titles.

Jacks was most famous for his amazing efforts in the gymnasium, where he repeatedly set records in the "gym tests", including 100 parallel bar dips in 60 seconds in the 1981 Challenge of the Champions, and 118 squat thrusts in the 1980 World Final. He was also very dominant in the weightlifting, canoeing and cycling events, rarely placing lower than second. Unfortunately, Jacks was never able to win the World Superstars title, being forced to miss the 1979 event through illness and finishing third in 1980. In 1981 he was beaten for the first time in Europe (by Keith Fielding) and would never again compete in Superstars.
