History
Henry DeLong was born December 9, 1905, in Spink County, South Dakota. He graduated from Redfield High School in 1924. DeLong earned a Bachelor of Science degree in agriculture from South Dakota State University in 1928 and a Bachelor of Science degree in agricultural engineering in 1938. He completed a Master of Science degree in agricultural engineering at the University of Minnesota in 1941. DeLong married Mary M. Louise Franks on July 28, 1933, in Fulton, South Dakota.
DeLong’s professional career was almost entirely associated with South Dakota State University. He began as a student research assistant and advanced through the faculty ranks, retiring as professor emeritus in 1973. His responsibilities included teaching, research, and departmental administration. DeLong served as head of the department from 1946 to 1956. He was among the first agricultural engineers recognized at the Fifth Annual Distinguished Engineers Banquet at South Dakota State University. DeLong gained international recognition for his classification of rammed earth, a construction method originally developed for affordable poultry housing. He credited this work to his collaboration with R. L. Patty and Patty’s research on pisé de terre, the French term for rammed earth.
Professor Henry DeLong died on November 22, 1988, at Brookings Hospital.
