John G. Kemeny

John G. Kemeny was a Hungarian-American mathematician, computer scientist, and educator who made foundational contributions to computer science and higher education. He is best known for co-creating the BASIC programming language and the Dartmouth Time-Sharing System, innovations that democratized access to computing. As the 13th President of Dartmouth College, he oversaw significant reforms, including the adoption of coeducation at the undergraduate level.

Early life and education

Born János György Kemény in Budapest in 1926, he emigrated with his family to the United States in 1940, fleeing the rise of Nazism in Europe. He attended George Washington High School in New York City before enrolling at Princeton University in 1943. His studies at Princeton University were interrupted when he was recruited to work on the Manhattan Project at Los Alamos under the supervision of Richard Feynman. After World War II, he returned to Princeton University, completing his undergraduate degree in 1947 and earning his Ph.D. in mathematics in 1949 under the renowned logician Alonzo Church.

Academic career

Kemeny began his academic career as an assistant to Albert Einstein at the Institute for Advanced Study in Princeton, New Jersey. In 1953, he joined the faculty of Dartmouth College as a professor of mathematics. He quickly rose to become chairman of the college's mathematics department, where he championed the integration of computing into the liberal arts curriculum. His scholarly work spanned mathematical logic, Markov chains, and finite mathematics, and he co-authored several influential textbooks with colleagues like J. Laurie Snell.

Development of BASIC and Dartmouth Time-Sharing System

In the early 1960s, Kemeny, alongside colleague Thomas E. Kurtz, sought to make computing accessible to all students, not just science and engineering majors. This vision led to the creation of the Dartmouth Time-Sharing System (DTSS), one of the first successful large-scale time-sharing systems. To enable easy interaction with DTSS, they invented the Beginner's All-purpose Symbolic Instruction Code (BASIC) in 1964. The simplicity of BASIC, which allowed students to write programs using teletype terminals, revolutionized computer education and became the gateway language for a generation of programmers, influencing the development of early microcomputers like the Apple II.

Presidency of Dartmouth College

Kemeny was appointed the 13th President of Dartmouth College in 1970, a tumultuous period marked by protests against the Vietnam War. His tenure was defined by progressive and transformative policies. Most notably, in 1972, he successfully advocated for Dartmouth to become fully coeducational, ending over 200 years as an all-male institution. He also established the Native American Program at Dartmouth College and championed increased diversity in the student body. His leadership modernized the Ivy League institution while navigating the financial challenges of the 1970s.

Later life and legacy

After stepping down from the presidency in 1981, Kemeny returned to teaching at Dartmouth College as a professor of computer science and mathematics. He continued to write and remained active in professional organizations, receiving the Computer Pioneer Award from the IEEE Computer Society in 1985. He died of heart failure in Hanover, New Hampshire in 1992. His legacy endures through the ubiquitous influence of BASIC on software development, the model of the Dartmouth Time-Sharing System, and the more inclusive and modern Dartmouth College he helped shape. The Kemeny's constant in Markov chain theory also bears his name. Category:American computer scientists Category:American mathematicians Category:Presidents of Dartmouth College
