Question: Who was the father of the man who performed on the concert album The Wall recorded in the city where uranium was discovered?

<P0-S0> His father, the son of a coal miner and Labour Party activist, was a schoolteacher, a devout Christian, and a Communist Party member. <P0-S1> Waters was born on 6 September 1943, the younger of two boys, to Mary (née Whyte; 1913–2009) and Eric Fletcher Waters (1914–1944), in Great Bookham, Surrey. <P0-S2> In the early years of the Second World War, Waters' father was a conscientious objector who drove an ambulance during the Blitz. <SEP> <P1-S0> The discovery of the element is credited to the German chemist Martin Heinrich Klaproth. <P1-S1> Klaproth assumed the yellow substance was the oxide of a yet-undiscovered element and heated it with charcoal to obtain a black powder, which he thought was the newly discovered metal itself (in fact, that powder was an oxide of uranium). <P1-S2> While he was working in his experimental laboratory in Berlin in 1789, Klaproth was able to precipitate a yellow compound (likely sodium diuranate) by dissolving pitchblende in nitric acid and neutralizing the solution with sodium hydroxide. <P1-S3> He named the newly discovered element after the planet Uranus, (named after the primordial Greek god of the sky), which had been discovered eight years earlier by William Herschel. <SEP> <P2-S0> as the center of the empire, early-ming nanjing had worldwide connections. <P2-S1> it was home of the admiral zheng he, who went to sail the pacific and indian oceans, and it was visited by foreign dignitaries, such as a king from borneo (boni 渤泥), who died during his visit to china in 1408. the tomb of the king of boni, with a spirit way and a tortoise stele, was discovered in yuhuatai district (south of the walled city) in 1958, and has been restored. <SEP> <P3-S0> marie skłodowska - curie was a polish - born french physicist and chemist who is famous for her pioneering research on radioactivity. <P3-S1> she and her husband are considered to have laid the cornerstone of the nuclear age with their research on radioactivity. <P3-S2> marie was fascinated with the work of henri becquerel, a french physicist who discovered in 1896 that uranium casts off rays similar to the x-rays discovered by wilhelm röntgen. <P3-S3> marie curie began studying uranium in late 1897 and theorized, according to a 1904 article she wrote for century magazine, ``that the emission of rays by the compounds of uranium is a property of the metal itself -- that it is an atomic property of the element uranium independent of its chemical or physical state. <P3-S4> ''curie took becquerel's work a few steps further, conducting her own experiments on uranium rays. <P3-S5> she discovered that the rays remained constant, no matter the condition or form of the uranium. <P3-S6> the rays, she theorized, came from the element's atomic structure. <P3-S7> this revolutionary idea created the field of atomic physics and the curies coined the word radioactivity to describe the phenomena. <SEP> <P4-S0> The show was held in Berlin on 21 July 1990, to commemorate the fall of the Berlin Wall eight months earlier. <P4-S1> A live album of the concert was released 21 August 1990. <P4-S2> The Wall – Live in Berlin was a live concert performance by Roger Waters and numerous guest artists, of the Pink Floyd studio album "The Wall", itself largely written by Waters during his time with the band. <P4-S3> A video of the concert was also commercially released.
