Economist. He gained recognition for his work as a modern-day economist and statistician, as well as a journalist and university-level educator. After earning a B.A. from Amherst College in 1860, he joined a law firm. During the American Civil War, he enlisted in 1862 in the United States Army. In 1864, he was captured at Petersburg but was released in a prisoner exchange. By the end of the war, he was brevetted Brigadier General at age 24, for the Army of the Potomac. After the war, he studied classical economics at Williston Seminary and Amherst College before teaching and becoming a journalist for the "Springfield Republican" newspaper. During his life, Walker was a prolific author, published at least ten textbooks, mainly on topics in economics. At that point, he accepted the position as head of the statistical bureau at the United States Treasury Department. Following being a very respected superintendent of the 1870 Federal Census, he was a strong supporter of the 1880 Federal Census, which obtained various stats on Americans for the first time. As an educator, he was a professor of political economics at Yale University from 1873 to 1881, before becoming one of the first presidents of the Massachusetts Institute of Technology (MIT) from 1881 to his death. He was a member of various professional groups, including being the president of the American Statistical Association (ASA) and the first president of the American Economic Association (AEA). Since 1947, the AEA has awarded the Walker Award in Economics. This award was the highest award to be offered to worthy candidates until the Nobel Prize opened a category for economics in 1969. His main economic theory was the "residual claimant theory" for paying wages, meaning all other debts should be paid, such as facility rent, interest to banks, and profits to shareholders, before paying the employees' wages, thus keeping the business healthy for all. His bust is on display at the Boston Public Library. He died from "apoplexy" or a stroke. He married Exene Evelyn Stoughton on August 16, 1865, and had two daughters and five sons.
