Background: John Kenneth Galbraith  (October 15, 1908 - April 29, 2006), also known as Ken Galbraith, was a Canadian-born economist, public official, and diplomat, and a leading proponent of 20th-century American liberalism. His books on economic topics were bestsellers from the 1950s through the 2000s, during which time Galbraith fulfilled the role of public intellectual. As an economist, he leaned toward post-Keynesian economics from an institutionalist perspective. Galbraith was a long-time Harvard faculty member and stayed with Harvard University for half a century as a professor of economics.
Context: Galbraith was born on October 15, 1908, to Canadians of Scottish descent, Sarah Catherine (Kendall) and Archibald "Archie" Galbraith, in Iona Station, Ontario, Canada, and was raised in Dunwich Township, Ontario. He had three siblings: Alice, Catherine, and Archibald William (Bill). By the time he was a teenager, he had adopted the name Ken, and later disliked being called John. Galbraith grew to be a very tall man, attaining a height of 6 feet 9 inches (206 cm).  His father was a farmer and school teacher. His mother, a homemaker and a community activist, died when he was fourteen years old. The family farm was located on Thomson Line. Both of his parents were supporters of the United Farmers of Ontario in the 1920s.  His early years were spent at a one-room school which is still standing, on Willy's Side Road. Later, he went to Dutton High School and St. Thomas High School. In 1931, Galbraith graduated with a Bachelor of Science in Agriculture from the Ontario Agricultural College, which was then an associate agricultural college of the University of Toronto. He majored in animal husbandry. He was awarded a Giannini Scholarship in Agricultural Economics (receiving $60 per month) that allowed him to travel to Berkeley, California, where he received Master of Science and Doctor of Philosophy degrees in agricultural economics from the University of California, Berkeley. Galbraith was taught economics by Professor George Martin Peterson, and together they wrote an economics paper titled "The Concept of Marginal Land" in 1932 that was published in the American Journal of Agricultural Economics.  After graduation in 1934, he started to work as an instructor at Harvard University. Galbraith taught intermittently at Harvard in the period 1934 to 1939. From 1939 to 1940, he taught at Princeton University. In 1937, he became a citizen of the United States and was no longer a British subject. In the same year, he took a year-long fellowship at the University of Cambridge, England, where he was influenced by John Maynard Keynes. He then traveled in Europe for several months in 1938, attending an international economic conference and developing his ideas. His public service started in the era of New Deal when he joined the United States Department of Agriculture. From 1943 until 1948, he served as an editor of Fortune magazine. In 1949, he was appointed professor of economics at Harvard.
