Input: Question: Who is the current president of the university that Haydock graduated from? Passage 1: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.
 Passage 2:Haydock was a graduate of Glasgow University and was a travelling salesman for the Clydevale Oil & Colour Company, Bridgeton. In September 1914, one month after the outbreak of the First World War, Haydock enlisted in the Queen's Own Cameron Highlanders. In January 1915, he was commissioned as a second lieutenant in the Cameronians (Scottish Rifles). Haydock saw action at Gallipoli and Palestine before being seriously wounded during an attack on Umbrella Hill during the Third Battle of Gaza on 1 November 1917. He did not return to his battalion until August 1918, after it had been deployed on the Western Front. Haydock was wounded during an attack on the Hindenburg Line, west of Quéant on 2 September 1918 and died the same day at a Casualty Clearing Station in Bailleulval. He was buried in Bac-du-Sud British Cemetery, Bailleulval.
 Passage 3:Fram Reykjavík won the second-tier championship of 1. deild karla in 2006 and finished 7th in the Landsbankadeild (the then name for the premier division) in 2007. They bought the Swedish striker Patrik Redo, whom they later had to sell to Keflavík Football Club. In 2008 Fram played their best season in many years when they finished 3rd in the Landsbankadeild. In 2009 the club was number 4, and played in the Icelandic Cup Final but lost to Breiðablik UBK in a penalty shootout. Now it seems as if Fram Reykjavík is back among the best again. Fram's woes continued in the spring of 2006. In 2008 things changed a lot though a new manager came that had been playing for Fram Reykjavík in the famous 86–91 team Þorvaldur Örlygsson. He started by buying Auðun Helgason, a former Icelandic international football player Assistant manager. For the third time in three years, a new coach would take the helm and most of the time it seemed as if nobody could lead Fram Reykjavík out of the dark. This time, however, it was a complete success. Fram Reykjavík won four straight games, gobbling up KR's lead as team number 3 in the table (a qualifying position for the UEFA Cup), and finally overtaking them. Fram Reykjavík against FH Hafnarfjörður where they won away which was for the first time in many years, the team that was supposed to be unbeatable they managed to win. The following weekend, Fram Reykjavík beat Keflavík, securing the club's third position in the league for the first time since 1992. Fram Reykjavík was back in European competition: the team that almost drew at Nou Camp 18 years ago was back, and there was more good news to come, Þorvaldur Örlygsson accepted a new offer to be the manager. The summer of 2009 came out to be not as good as expected in Úrvalsdeild Fram Reykjavík finished 4th, which was an obvious disappointment. And in Visa-Bikar 2009 Fram Reykjavík made it to the finals but lost in penalty kickout against Breiðablik UBK where Paul McShane missed the last penally for Fram Reykjavík, in UEFA Cup 2009 Fram won The New Saints F.C. easily in the first round but in the second round Fram Reykjavík traveled to Czech Republic to play Sigma Olomouc the first match went 1–1 where Sigma scored a goal almost in the last second of the match. The second match Sigma Olomouc won but Fram Reykjavík was told to have played maybe their best matches of the summer there and they showed that on a good day they could play like the big teams in Europe. Before the 2009 season Þorvaldur Örlygsson brought several new players to Fram Reykjavík, one of them being Jón Gunnar Eysteinsson who Þorvaldur Örlygsson knew well from Fjarðabyggð, he was supposed to come instead of Auðun Helgason that went to Grindavík and Some other players like the English brothers which both started their career playing for Chelsea F.C., Joe Tillen and Sam Tillen the team of 2010 was one of the youngest teams ever in Icelandic football, the oldest player was 25 years old. Still it was a summer of disappointment finishing 5th.
