question:
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:
Question: Is the person who taught Midori violin at the Pre-College Division of Juilliard School still teaching? Passage:Midori gave her first public performance at the age of six, playing one of the 24 Caprices of Paganini in her native Osaka. In 1982 she and her mother moved to New York City, where Midori started violin studies with Dorothy DeLay at Pre-College Division of Juilliard School and the Aspen Music Festival and School. As her audition piece, Midori performed Bach's thirteen-minute-long Chaconne, generally considered one of the most difficult solo violin pieces. In the same year, she made her concert debut with the New York Philharmonic under Zubin Mehta, a conductor with whom she would later record on the Sony Classical label. In 1986 came her legendary performance of Leonard Bernstein's Serenade at Tanglewood, conducted by Bernstein. During the performance, she broke the E string on her violin, then again on the concertmaster's Stradivarius after she borrowed it. She finished the performance with the associate concertmaster's Guadagnini and received a standing ovation. The next day The New York Times front page carried the headline, "Girl, 14, Conquers Tanglewood with 3 Violins".
