to compete with the free prices of the "aid" sent and therefore they were not able to sustain themselves or invest the money they made from crops back into the economy. He theorized that if the U.S. instead used its resources to help educate these rural producers and provide them with technology and innovations they would be more stable, productive and self sustaining in the long run. This was another key part of his work "Investment in Human Capital". Nobel Memorial Prize in Economic Sciences Schultz was awarded the Nobel Prize jointly with Sir William Arthur Lewis for his work in development economics, focusing on the economics of agriculture. He analyzed the role of agriculture within the economy, and his work has had far reaching implications for industrialization policy, both in developing and developed nations. Schultz also promulgated the idea of educational capital, an offshoot of the concept of human capital, relating specifically to the investments made in education. Family and personal life Schultz married Esther Florence Werth (1905–1991) in 1930. She was born and raised on a farm near Frankfort, South Dakota of German parents, who encouraged her to pursue schooling. Werth was the first in her family to attend college, receiving a bachelor's degree in commercial science from South Dakota State College in Brookings in 1927, and subsequently worked as a school teacher in Waubay, South Dakota from 1927 to 1929 and then in Gregory, South Dakota from 1929 to 1930. Werth shared Schultz's background in agriculture and commitment to ideals of education and economic development, and throughout his career worked as a primary editor of his published works. In his Nobel Prize Lecture, he acknowledged her contributions thus: "I am also indebted to my wife, Esther Schultz, for her insistence that what I thought was stated clearly was not clear enough." The couple was survived by two daughters and one son. Legacy Schultz received eight honorary degrees in his career. He had the distinction of being the first South Dakota State University graduate and the second South Dakotan to win a Nobel Prize after Ernest Lawrence winner of the 1939 Nobel Prize for Physics. Between 2012 and 2013, South Dakota State University built the Theodore W. Schultz Hall, a residence hall for students pursuing degrees in agriculture. Schultz also was awarded the Francis A. Walker Medal in 1972, which is the highest award given out by the
