150 people who shaped Iowa State

In anticipation of the 150th anniversary of Iowa State University's founding in 1858, VISIONS proudly presents this list of 150 "VISIONaries" -- individuals who built Iowa State, from its earliest beginnings as an agricultural college, to today's university of science and technology.

The people on this list were chosen for their leadership, their historical significance, their uniqueness, and their professional accomplishments. When compiling the list, the VISIONS staff used the following criteria:

• The person must have been (or cur- rently be) an ISU student, alum, faculty, or staff member.
• The person may be living or deceased.
• The person must have made a last- ing and/or meaningful contribution to Iowa State, the state of Iowa, the world, or to her/his chosen profes- sion.
• If the person is a former faculty/staff member, the significant contribution must have been made while at Iowa State.

As the list was being compiled, it became obvious that hundreds – even thousands – of Iowa State faculty and alumni deserved to be included based on this criteria. It was no easy task reducing the number to just 150. The final list represents people from a wide variety of disciplines and historical eras, and who have made unique contributions to this university and beyond. It is our hope that the list inspires lively discussion on campus and among alumni.

Please note that none of Iowa State’s presidents are included on this list.

Terry Anderson Thomas Sutherland
Journalism/political science 1974 MS animal science 1956, Ph.D. 1958

Terry Anderson, Middle East bureau chief for the Associated Press, didn’t know Tom Sutherland, dean of agriculture and food science at American University in Beirut, Lebanon, until he landed in Anderson’s holding cell in Beirut in 1985. But they got to know each other, held hostage for nearly 2,400 days by their captors. Back in Ames, campanile bells tolled and yellow ribbons were tied to trees as the university community awaited word of their plight. When Sutherland and Anderson were released in 1991, the campus welcomed home two true American heroes. Anderson spoke at ISU’s Memorial Union in November 1993: “My life is truly full of joy. I wouldn’t wish for anybody to go through what I did. But I do wish you could feel as I do today, and every day.”

Dwight Ink
Political science 1947

Dwight Ink worked for every U.S. president from Eisenhower to Reagan. His roles in federal government were as diverse as the presidents he served – from urban affairs, environment and energy, education, and anti-poverty to foreign aid, arms reduction, and disaster reconstruction. As the director of the Atomic Energy Commission, Ink worked on the development of naval and space nuclear development. After the great Alaska earthquake of 1964, President Johnson dispatched Ink to supervise the reconstruction of Valdez. He also helped establish the new Department of Housing and Urban Development and the Environmental Protection Agency. In the Ford Administration, Ink managed oil conservation after the Arab embargo and served as acting administrator of the General Services Administration. With President Carter, he was instrumental in the design of the Civil Service reform, the first major overhaul of that federal system in 100 years. Today Ink is retired and lives in the Washington, D.C., area.

Frederick Douglass Patterson
DVM 1923, MS veterinary pathology 1927

Frederick Douglass PattersonFrom a humble upbringing in the early 1900s, Frederick Patterson grew to become one of the most influential leaders – and most successful fundraisers – in the history of African-American education. At Iowa State, Patterson was one of the earliest African-American students to earn a veterinary degree. He became the third president of Tuskegee Institute (now University) in 1935, where he oversaw the establishment of the School of Veterinary Medicine and introduced the Tuskegee Airmen flight training program. Patterson founded the United Negro College Fund in 1946, an organization that has now raised more than $1 billion for student aid. In 1987, he was awarded the Presidential Medal of Freedom in honor of his many years of work in education and philanthropy for historically black colleges and universities.

Benjamin Gue
Were it not for the passion, determination, and youthful exuberance of Benjamin Gue, Iowa State may not have become the university it is today. Gue was a young, aggressive representative in the Iowa General Assembly in 1856 when a bill was presented to establish an agricultural college in the state of Iowa. Gue fought almost unbeatable odds to win favor with the legislature to provide a “college where the sons of farmers and others of moderate means could be aided to secure an education equal to that afforded to professional men at the state university.” He fought again a few years later when that decision looked likely to be repealed due to state budget constraints. Gue was rewarded in 1866 by being elected president of the board of trustees of the new agricultural college, and again facing considerable opposition, he secured the admission of women on an equal basis with men.

Ada Hayden
Botany 1908, Ph.D. 1918

Historians will forever remember Ada Hayden as the first woman (and only the fourth person, male or female) to earn a Ph.D. at Iowa State College. But her legacy does not end there. Hayden became assistant professor of botany in 1920, teaching classes until 1934 when her appointment was changed to a research position in the Agriculture Experiment Station. She became curator of the college’s herbarium, photographing and illustrating native plants. During her time at Iowa State, she added more than 40,000 specimens to the herbarium, which is now named in her honor. Hayden was devoted to prairie preservation and research. She campaigned for a system of prairie preserves, one of which was later named the Ada Hayden Prairie Preserve by the Iowa Conservation Commission. Today, the Ada Hayden Heritage Park just north of Ames also bears her name and continues her legacy.
