Passage: The original catalyst for development was the ill-fated vanity project by Lord Kensington (died 1852) which consisted of the two-mile conversion of the insanitary Counter's Creek into the Kensington Canal (1826 onwards), followed by its eventual replacement first by "Mr Punch's railway", opened in 1844 and next, by the Metropolitan District Railway in 1865–69, which eventually became London Underground's District Line and was joined after 1907 by the Piccadilly line. Meanwhile, the congestion apparent in London and Middlesex for burials at the start of the century was causing public concern not least on health grounds. In 1837 a decision was made to lay out a new burial ground on the edge of Earl's Court in an outlying area of Brompton. The moving spirit behind the project was the engineer, Stephen Geary. It was necessary to form a company in order to get parliamentary permission to raise capital for the proposal. Securing the land – some 40 acres – from local landowner, Lord Kensington and the Equitable Gas Light Company, as well as raising the money proved an extended challenge. After two years the cemetery was duly established by Act of Parliament and laid out in 1839, it opened in 1840, originally as the West of London and Westminster Cemetery. It was consecrated by Charles James Blomfield, Bishop of London in June 1840, and is now one of Britain's oldest and most distinguished garden cemeteries, served by the adjacent West Brompton station.

Passage: After the war ended in May 1945 Gräf returned home in August 1946. Home was now in the Soviet occupation zone of what remained of Germany. During the next few years, under Soviet Military Administration, the region would become the Soviet sponsored German Democratic Republic, formally founded in October 1949, but in reality the creation of the new state was an iterative process. Already in April 1946, the merging of the old Communist Party (KPD) and more moderately left wing SPD into the new SED created the basis for a return to one-party government. Hugo Gräf arrived back as a long-standing member of the Communist Party, now no longer illegal in Germany, and like thousands of others, lost no time in signing over his membership to the new Socialist Unity Party of Germany (SED / Sozialistische Einheitspartei Deutschlands). In 1946 he became a spokesman/consultant of the health department of the Central Secretariat with the interim administration, having become a department head by 1948. He was one of the founders of the Health Service of the Trade Union Federation (FDGB / Freier Deutscher Gewerkschaftsbund), and on 5 July 1949 he was appointed its first president, serving in this position till 1951.
