Undergraduate student enrollment doubled to more than 1000 students. The national Egg Industry Center and the U.S. Pork Center of Excellence were established at ISU during his tenure.
Susan J. Lamont, 2001 -2003
An Illinois native, Sue came to Iowa State in 1983 to lead the poultry genetics program after earning her Ph.D. at Illinois and conducting postdoctoral studies at the University of Massachusetts. She devoted her efforts to graduate education and a world-renowned program of research in molecular genetics of poultry. As chair, she guided the department through a period of extreme budget constriction, with a focus on high-priority mission areas that provided a strong foundation for continued excellence and future growth. Sue was the first female tenured faculty member and the first female chair of the department.
Dennis N. Marple, 1992-2001
As Head of the Department of Animal Science beginning in 1992, Denny Marple oversaw the planning and construction of the $20-million addition that was opened November 1998. Denny grew up on a northwest Iowa farm and entered Iowa State University in the curriculum of electrical engineering. That strong farm background prevailed, however, and he graduated in animal science. His graduate work at Iowa State and Purdue was in swine. He headed the animal and dairy science department at Auburn University before coming to Iowa State. Denny led the faculty with innovation that kept the department at the forefront as a leader in animal science land-grant schools.
Solon A. Ewing, 1973-1992
As the eighth department head, "Bud" Ewing led the faculty longer than any previous head. His efforts in developing value-added product processing and marketing, systems analyses and computer applications for refined management decisions in animal production and marketing, and molecular biology benefited all of Iowa animal agriculture. He was able to attract and build a quality faculty, bringing recognition to the department and prestige and international prominence to the university. He provided significant direction in both concept and development of several centers and facilities at Iowa State University, including the Meat Laboratory, Meat Export Research Center, Swine Nutrition and Management Research Center, Iowa Livestock Extension Initiative and Linear Accelerator Facility.
Lanoy N. Hazel, 1967-1973
A Texas panhandler by birth, Hazel came to Iowa State in 1939 with an M.S. degree in genetics to study with Jay L. Lush who had written a book that puzzled Hazel. Thus began a long and close relationship that continued over three decades. This was also the beginning of a research and teaching career filled with seminal developments that changed both the practices of animal breeding and the scientific methodologies supporting breeding research. In 1968, Hazel reluctantly shifted his focus from direct teaching and research and became an administrator, Head of the large and diverse Animal Science Department at Iowa State University, until 1973 when he retired.
Leslie E. Johnson, 1954-1967
A native Iowan from Mahaska County, Johnson attended Penn College for two years and then enrolled at Iowa State College. He graduated in 1929 and marrying his college sweetheart in 1930. His M.S. degree came in 1938 and a Ph.D. degree in 1941, all in animal science. After heading animal science at South Dakota State University and work for the USDA in Nebraska, he returned to Iowa State College in 1954 as Head of the Department of Animal Husbandry. His twelve years of leadership were marked by tremendous growth and laid the foundation still in place today. Especially, he attracted top men of talent and ability. Departmental focus became sectional rather than unified. Undergraduate teaching improved, and graduate student enrollment grew. In 1959 the centennial celebration of Iowa State College saw the name change to Iowa State University. In 1962, the Department of Animal Husbandry became Department of Animal Science. All livestock was moved off campus in 1965 to the Animal Science Teaching Farm and the department moved into Kildee Hall, with Dean Kildee attending.
Phineas S. Shearer, 1935-1954
Born in Marshall County, Iowa, he earned his B.S. degree at Iowa State in 1912 and his M.S. from Wyoming in 1932. After one year at Nebraska he joined the faculty at Iowa State in 1913. As an instructor at ISC, he also took graduate courses, where, with C. N. Arnett, an instructor in livestock management, they conceived the idea of making campus livestock classes competitive. They formed the first stock show, now known as the "Little International" in which animal husbandry students fit and show college-owned livestock. From 1919-1934, he served as coach of the livestock judging team, during which period Iowa State's team placed first three times at the International Livestock Exposition in Chicago, and only once below tenth place in the 16 years. In 1932 Shearer's team became the first judging team to win top honors at both the International and the Royal. As head of the department, research programs emphasized meat production, genetic improvement of livestock and swine and sheep feeding.
Henry H. Kildee, 1918-1935
Born to a farm couple at Osage, Iowa, Dean Kildee was a dairy farmer. Graduating with a B.S. degree from Iowa State in 1908, he joined the staff of ISC in 1909 and the following year was made head of dairy husbandry. He went to the University of Minnesota as head of dairy industry. He returned to ISC in 1918 as head of animal husbandry and a year later was also named vice-dean of agriculture for resident instruction. Students, dairy cattle breeders, and judging of most species of livestock were his loves, to which he devoted his keen insights and patient time. A most beloved teacher, he guided and inspired students and breeders of dairy cattle, judged shows, served on committees of true type, unified score cards, and type classification, and was a type classifier with Holsteins and Jerseys.
W. H. Pew, 1912-1918
An only child of a prominent steel manufacturing president at Youngstown, Ohio, Bill Pew grew up on a farm and early on was fond of the animals. His truly cultured and refined parents did not try to change him but encouraged his desire to be a stock farmer by sending him to The Ohio State University to study agriculture. But he followed the advice of Horace Greeley, Go West, young man, go West and became a student at Iowa State College, an institution known the world over for its practical live stock instructional work. A member of a well-known social fraternity at OSU, he did not see fraternity life at Iowa State, but instead helped at the swine barns. Graduating from Iowa State in 1907, he became Head of the Animal Husbandry Department of New Hampshire State College. He returned to Iowa State in 1909 and in 1912 was named Head. He was known as a very able administrator. In 1918 he resigned to return to his father's farm where he rose to top breeder status in Shorthorn cattle and Poland China hogs. He was a noted judge as well. At the 1926 Philadelphia Exposition he was swayed to go to the 5,000-acre Briarcliff Farm in western New York with a herd of 1,000 purebred Aberdeen Angus cattle, where he built the largest such herd in the country. He was very active in 4-H work.
W. J. Kennedy, 1902-1912
A Canadian who went to Illinois, Kennedy distinguished himself by producing the top steer at the very first International Live Stock Exposition at Chicago. His team also took home the judging trophy in 1900, thereby catching the eye of C. F. Curtiss, a director of the Exposition. Kennedy continued to train top judging teams for Iowa State in 1901, 1902 and 1903, winning permanently for the school the magnificent J. A. Spoor Trophy, a Bonheur bronze of the bull in defiance stance, still exhibited with great pride by the department. After heading the animal husbandry department for four years, he was named vice direction of the experiment station by Dean Curtiss in 1906. In 1912 he was named head of the Extension Department. Kennedy is also noted for hiring R. K. Bliss who worked in ISU Extension for over 50 years.
Charles F. Curtiss, 1889-1902
The first head of animal husbandry at Iowa State College, Dean Curtiss was born in Illinois but grew ups on a farm 10 miles north of the Iowa State Campus. In 1887, he earned his B.S. from ISC and joined the faculty in 1891. Curtiss was made professor of animal husbandry in 1896 and head in 1889. He received his M.S. from ISC in 1894, one of three granted before the turn of the century. When Curtiss joined the faculty, there was one course and one instructor in agriculture. He formulated a four-year curriculum adopted in 1892. Curtiss developed the teaching herds, first importing a Scottish Shorthorn bull. He bought cows and sheep, as well. He published bulletins regularly on many topics to help Iowa farmers, then the several staff members of animal husbandry began publishing. He promoted ISC with the livestock judging teams and the grand championships won by fat stock at the major expositions, Chicago in particular. From 1900 to 1932, the year he retired, Iowa teams were first one-third of the time and in the top three almost two-thirds of the time. His love of animals and agriculture propelled him into the deanship where he made science a top priority for the college.
