Ronald Graham

Ronald Graham is a well-known American mathematician and computer scientist who has written extensively on a wide range of topics stemming from computational complexity theory and discrete mathematics. Throughout his life, he has received numerous awards, including the National Medal of Science in 1999 and the Steele Prize for Mathematical Exposition in 2004.

Graham was born on October 31, 1935 in Taft, California. At an early age, he showed a keen interest in mathematics and related topics. When he was 17, he enrolled in California Institute of Technology, where he earned his Bachelor’s and Master’s degrees in mathematics. Following his graduation in 1957, Graham became a research mathematician at Bell Laboratories in Murray Hill, New Jersey, where he worked until his retirement in 1999.

Throughout his career at Bell Laboratories, Graham has made numerous contributions to mathematics, computer science, and theoretical computer science. He is best known as the father of “Ramsey Theory,” a branch of mathematics concerned with the structure of large networks. In this field, Graham has established foundational results that have had far-reaching implications. He has also contributed extensively to the field of algorithms and data structures. Other areas of tremendous influence have included graph theory, computational complexity theory, and finite-group theory.

In recognition of his work, Graham has received numerous prestigious awards, such as the National Medal of Science in 1999 and the Steele Prize for Mathematical Exposition in 2004. Additionally, he was elected as a Fellow of the American Mathematical Society in 2012 and appointed to the National Academy of Sciences in 1983. Moreover, he was elected as a Fellow of the Association for Computing Machinery in 1961, one of the highest honors in the field of Computer Science.

Parallel to his esteemed mathematical career, Graham also has written numerous books and papers. He is perhaps best-known for his textbooks “Concrete Mathematics” and “Fundamentals of Mathematics”, which have become some of the most widely-used mathematics textbooks in the United States. He also wrote and co-wrote nearly 500 papers, most of which have become standard reading in modern mathematics and computer science curricula.

Although Graham stopped short of formally achieving a Doctorate in Mathematics, he has nonetheless devoted his life to researching and teaching mathematics and computer science. He has had a far-reaching influence on the research and study of mathematics and computer science, and his work will continue to shape and influence many discipline for generations to come.
