Jay was born on February 15, 1880, in Otoe County, Nebraska, United States; the son of James H. Davidson and Margaret Jan Davidson. He grew up in the southeastern Nebraska town of Douglas.
Jay attended area schools and graduated from Douglas High School in Douglas, Arizona, United States. Later, he studied at the University of Nebraska, in Lincoln, Nebraska, United States. In 1904 he received a Bachelor of Science degree in mechanical engineering. In 1914 he earned an agricultural engineering degree from the University of Nebraska. In 1931 he received a Doctor of Philosophy degree.
As an undergraduate, Jay was a student assistant in a machine shop. He worked in a locomotive shop and as a draftsman, gaining additional skills and understanding of metalwork and machinery. In 1904 Jay spent the summer at Deere and Company and worked as a service agent for International Harvester in 1905 before beginning a 50-year academic career in the fall of 1905 when he joined the faculty of ISC in agricultural engineering, a position he held until 1915.
Jay published more than 25 extension bulletins on topics such as silos, creameries, and farm structures. He also received nine patents for power measuring devices and farm machinery. Davidson worked with faculty and students to exhaustively review and test farm machinery and wrote a definitive volume titled Farm Machinery and Farm Motors in 1908. In 1910, under Davidson’s leadership, ISC granted the first degree in agricultural engineering. The degree program served as a model for other institutions, and its graduates influenced farm machinery production across the country.
Davidson participated in a multitude of professional academic groups. Jay judged machinery at the Winnipeg Tractor Trials in 1909, 1910, and 1911, formative years of tractor development. In the fall of 1915, Davidson left ISC for the University of California at Davis but returned to Ames in 1919 with an appointment as chair of the agricultural engineering department. He retired from active teaching in 1946.
Davidson served the federal government and private industry as a consultant and adviser. His reputation gained him an appointment to conduct a survey of farm machinery for the U.S. Department of Agriculture in cooperation with the National Association of Farm Equipment Manufacturers while on leave from ISC. In 1929 he traveled to the Soviet Union as part of the American Commission studying colonization in the eastern Soviet Union. He served as a consultant to the War Production Board during World War II for the appropriation of steel for the production of agricultural machinery. After the war, he advised the United Nations on the allocation of machinery for the liberated European nations. He counseled the federal government and chaired an advisory group of agricultural engineers to help “Westernize” Chinese agriculture in 1947 as part of a group sponsored by International Harvester. The visit was cut short by the fall of Chiang Kaishek. He joined Ford Motor Company’s Dearborn Farm Equipment as a consultant beginning in 1951. Davidson retained a home in Ames until 1956. He died at age 77, after a prolonged illness, in Denver, Colorado.
Jay was president of the now-defunct Sigma Tau engineering honorary fraternity and held memberships in the Iowa Engineering Society and other honor societies, including Tau Beta Pi, Sigma Xi, and Gamma Sigma Delta.
On June 14, 1905, Jay married Sarah Jennie Baldridge at her parent's home. They raised two daughters.
