Question: How old was Walter's oldest son when Walters passed away? Passage:Walter was born in Kansas City, Missouri, United States, in 1910. His ancestry was German/British on his father's side, and American/British on his mother's side. He was brought to England in 1915, and educated at Westminster School and afterwards in King's College, Cambridge, in 1931. He failed to obtain a research fellowship in Cambridge and so turned to doing basic and applied neurophysiological research in hospitals, in London, from 1935 to 1939 and then at the Burden Neurological Institute in Bristol, from 1939 to 1970. He also carried out research work in the United States, in the Soviet Union and in various other places in Europe. He married twice, had two sons from his first marriage, and one from the second. According to his eldest son, Nicolas Walter, "he was politically on the left, a communist fellow-traveller before the Second World War and an anarchist sympathiser after it." Throughout his life he was a pioneer in the field of cybernetics. In 1970, he suffered a brain injury in a motor scooter accident. He never fully recovered and died seven years later, on May 6, 1977.

Question: Who was the leader of the country that defeated Romania 7-0 in an Olympic qualification match? Passage:Romania started Olympic hockey in 1964 in the B division. In the tournament, the team finished 12th out of 16 teams and managed 3 wins against Austria, Italy, and Hungary also with a tie against Yugoslavia. In 1968, Romania lost its qualification match against West Germany 7–0 and was forced to compete in the B division again. In the first two games, Romania beat Austria 3–2 and the Host, France 7–3. They lost their next three games and finished 12th out of 14 in the standings. After skipping the 1972 competition, Romania returned for the 1976 tournament. This time Romania played Poland in the Qualification round and lost 7–4, keeping them in the B division once again. However, Romania battled back and won 4 of 5 games with only one loss against Yugoslavia, still winning the division. The team finished 7th out of 12. In 1980, Romania was able to play with the top teams and was put into the Blue Division group, along with tough opponents such as Sweden, Czechoslovakia, and USA. In the first game Romania was down 4–2 to West Germany, but managed to score 4 goals to beat the former bronze medallists 6–4. In their next game Romania got shut out by Sweden 8–0. The Swedes scored 3 goals in the first period which left Romania out of it. After a lopsided loss to Czechoslovakia (7–2) the team then took on USA. The US jumped out to a 2–0 lead in the first period and added two more to it to lead 4–1 after two periods. Unlike other teams that the US had faced, the Romanians fought strong in the third period, despite being outshot 15–3, and scored a goal. The final score was 7–2. Romania played Norway for their final game, who had lost all four of their past games and had no chance to advance to the Medal Round. Romania fell behind less than a minute into the game, but stormed back to take the lead 3–1 in the third period. The Norwegian team battled back though, and scored once with a minute and a half left to play, and scored once more to tie it with only 29 seconds left. This tie still gave Romania one point but they had been hoping for a win. They finished the tournament with a 1–3–1 record, and were ranked 8th out of 12, just beating the Netherlands, West Germany, Norway, and Japan. This was the last time that the Romanians competed in the Olympic tournaments.
