Claude Emerson Welch Jr., State University of New York (SUNY) at Buffalo (UB) Professor of Political Science and SUNY Distinguished Service Professor of Political Science, was born on 12 June 1939 in Boston, Massachusetts, to Dr. Claude E. Welch, Sr., and Phyllis Paton Welch. The younger Welch "had the values of hard work and respect for others instilled him from an early age." His father worked his way through Harvard Medical School and served as a front-line surgeon in World War II. In his medical career, he became "a fixture at Massachusetts General Hospital for more than 40 years, was an innovative surgeon, a tireless worker, prolific researcher and an advocate of building strong ties with his patients, themes that would come to be synonymous with his...son."

Welch had four children with his late wife Nancy, who died in 1979. His son is Chris Welch, and his three daughters are Sarah Welch, Martha Dyer, and the late Elisabeth Ann (Lisa) Welch, who died in an alpine accident in September 2017. The Welch family maintains a camp on Lake Winnipesaukee in New Hampshire. In May 2020, Welch moved to Auburndale, Massachusetts, a suburb of Boston.

In 1981, Welch married Jeannette Marie Ludwig (September 29, 1949 – July 29, 2018), who was also a professor at UB. Welch and Ludwig divided their time between their homes in Amherst and the Chautauqua Institution. They donated their home to the Chautauqua Foundation and are members of the Eleanor B. Daugherty Society.

Welch's scope of interest extends globally. He and Ludwig traveled to more than 25 countries on five continents. They became avid photographers, and their collection of more than 2000 images, complete with detailed descriptions, is preserved in the digital collection of the University at Buffalo Libraries. Based on these images, the library maintains an exhibition titled Wayfarers: Selected Images from the Welch-Ludwig Collection . Welch and Ludwig also created a scholarship for students studying abroad, the Welch-Ludwig Fund for International Study.

Education Welch attended private schools from fifth grade on. He went to Belmont Hill School, Belmont, Massachusetts, where he received academic awards for Biology, French, Latin, and general scholarly excellence. In his senior year, Welch received the Headmaster's Award for Outstanding Student and graduated summa cum laude.

Welch was admitted to Harvard College, the undergraduate liberal arts college of Harvard University, in 1957 at age 18, graduated magna cum laude, and was elected to Phi Beta Kappa. He was elected President of The Harvard Crimson in 1960. Responding to the political upheaval in Africa where countries were fighting for independence, Welch focused his studies on Africa and human rights. His undergraduate honors thesis examined the impact of international law on South Africa's administration of South-West Africa (now Namibia) from the end of World War I to 1961.

Continuing with postgraduate studies at Oxford University, Welch earned his PhD in 1964. In an interview with UB Honors Today, UB's honors alumnae magazine, he explained that he did his dissertation research in West Africa, wrote the final draft on location, and mailed it to his committee. His interest in African politics and human rights formed the basis for his career.

Teaching career For more than 50 years, Welch taught political science at UB and lived in Amherst, New York, a suburb of Buffalo, New York. In 1964, Welch accepted a position in the political science department at the University at Buffalo, the largest and most comprehensive campus within the SUNY system. He rose rapidly in the academic ranks, serving as assistant professor from 1964 to 1968, associate professor from 1968 to 1972, full professor from 1972 to 1989, and as SUNY Distinguished Service Professor until his retirement in 2017. He was selected one of nine faculty members from the SUNY system to serve on the university-wide Advisory Council on Distinguished Service Professorships, 2009–12. His international teaching included a semester at the Singapore Institute of Management and part of a summer course at the International Institute of Human Rights, Strasbourg, France.

Welch became a mentor and renowned professor and took an active role in graduate as well as undergraduate education. His warm and enthusiastic personality and his intellect created an environment in which students explored the issues of the day, and his involvement in university activities demonstrated his devotion and attention to his students and their regard for him. In 2016 Welch received the President's Medal at the University at Buffalo, given "in recognition of signal and extraordinary service to UB." The citation praised his "major contributions to the development of, or quality of life within, the University."SUNY at Buffalo. UB Now. September 7, 2017

Welch's teaching responsibilities included African politics, civil-military relations, human rights, international law, political change, and world civilizations since 1500. He directed independent study and thesis and dissertation guidance. Since 1969, he participated in about 60 dissertation committees, chairing more than 30 of them, and he served as an outside reader for other departments at UB as well as other universities, for example, in Canada and South Africa. In addition, Welch taught at the Global Perspectives Academy and presented special seminars for the University Honors Program: Africa through Novels and Films, International Human Rights, and Women's and Men's Language (with Jeannette Ludwig).

Welch took special pride in teaching. In 2015, he told UB Honors Today that his teaching philosophy is "Let each become what they are capable of being. I try to build up a sense that, yes, individuals have made a difference, and you can do so, too. One of the objectives I see in my teaching is empowerment of students through knowledge, but also through a sense that they can be inspired by learning about others."

Welch's academic interests focus broadly on political transitions, particularly in developing countries, most notably in Africa. Welch published 14 books that demonstrate his expertise in African politics, civil-military relations, and human rights.
