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: How many people lived in the Massachusetts Bay Colony the year that Hutchinson was banished from there? Passage:John Cotton and Anne Hutchinson regarded preparationism as a covenant of works, a criticism that was one of the causes of the Antinomian Controversy, which led to Hutchinson being banished from the Massachusetts Bay Colony in 1638. Historians have debated the factors in Hutchinson's downfall, including issues of politics and gender; but intellectual historians have focused on theological factors, including preparationism, antinomianism, mortalism, and the idea of sanctification being evidence of justification. Harvard University historian Perry Miller views the incident as a "dispute over the place of unregenerate human activity, or 'natural ability', preparatory to saving conversion." Similarly, Rhys Bezzant sees the Antinomian crisis as pitting Hutchinson and others against "the defenders of preparationist piety." Bezzant goes on to argue that Jonathan Edwards distanced himself from his grandfather Solomon Stoddard's "preparationist model of conversion."

He completed naval aviation jet training at Naval Air Station Kingsville, Texas, receiving his aviator wings in May 1969. He was then assigned to the Advanced Jet Training Command (VT-21) where he served as an instructor from May 1969 to March 1971.
