Question: What electoral ward of Manchester, England, did Leonard "Len" Benker Johnson spend time in prior to World War II?

<P0-S0> Leonard "Len" Benker Johnson (22 October 1902 – 28 September 1974 (aged 71)) born in Clayton, Manchester was an English professional middle/light heavyweight boxer of the 1920s, and 1930s, who won the Australian version of the British Empire middleweight title in 1926. <P0-S1>  Johnson (who was of mixed race) was denied the opportunity to fight for championships in Great Britain because of the colour bar that existed in boxing at that time. <P0-S2>  He was managed by his father Bill Johnson. <P0-S3>  Len Johnson was also a member of the Communist Party of Great Britain (joining the party in 1944 and later writing a boxing column for the party newspaper "The Daily Worker"), a trade unionist, a community leader in Moss Side, a local civil rights activist, and attended the 5th Pan-African Congress in Manchester. <P0-S4>  Johnson fought on boxing booths in the 1920s, and from 1930 to 1939 owned his own travelling booth. <P0-S5>  Just prior to the outbreak of World War Two Johnson briefly tried his hand at professional wrestling, but once war came he lost interest in both boxing and wrestling, and sold his booth. <P0-S6>  During World War Two Johnson was a member of the Civil Defence heavy Rescue Squad in Manchester. <P0-S7>  Following the Second World War, he was a co-founder of the New International Society in Manchester, which provided a vehicle for black political and social self-organisation in the city and campaigning against racism at home and abroad, including organising a concert and a rally featuring Paul Robeson in support of the Trenton Six, which were both attended by 10,000 people. <SEP> <P1-S0> Coldhurst (or more rarely Cold Hurst) is an area of Oldham, and an electoral ward of the wider Metropolitan Borough of Oldham, in Greater Manchester, England. <P1-S1>  At the time of the United Kingdom Census 2001, it had a population of 11,935, increasing to 13,201 at the 2011 Census. <P1-S2>  The electoral ward spans most of Oldham's town centre, although the name Coldhurst conventionally applies to the area immediately north of the centre. <P1-S3>  The district of Westwood and a small adjoining part of Chadderton in the Busk area also lie within the Coldhurst ward district. <SEP> <P2-S0> Moss Side is an inner-city area and electoral ward of Manchester, England. <P2-S1>  It lies 1.9 mi south of Manchester city centre and had a population of 18,902 at the 2011 census. <P2-S2>  Moss Side is bounded by the neighbourhoods of Hulme to the north, Chorlton-on-Medlock, Rusholme and Fallowfield to the east, Whalley Range to the south, and Old Trafford to the west. <SEP> <P3-S0> Ward Leonard Control, also known as the Ward Leonard Drive System, was a widely used DC motor speed control system introduced by Harry Ward Leonard in 1891. <P3-S1>  In early 1900s, the control system of Ward Leonard was adopted by the U.S. Navy and also used in passenger lift of large mines. <P3-S2>  It also provided a solution to a moving sidewalk at the Paris Exposition of 1900, where many others had failed to operate properly. <P3-S3>  It was applied to railway locomotives used in World War I, and was used in anti-aircraft radars in World War II. <P3-S4>  Connected to automatic anti-aircraft gun directors, the tracking motion in two dimensions had to be extremely smooth and precise. <P3-S5>  The MIT Radiation Laboratory selected Ward-Leonard to equip the famous radar SCR-584 in 1942. <P3-S6>  The Ward Leonard control system was widely used for elevators until thyristor drives became available in the 1980s, because it offered smooth speed control and consistent torque. <P3-S7>  Many Ward Leonard control systems and variations on them remain in use.
