American mathematician and computer scientist Donald Knuth is famous for his significant contributions to computer science and for creating TeX and Metafont typesetting programs. Throughout his lifetime, he has devoted his life’s work to the mathematical study of how algorithms work and how much resources they require. This book series, “*The Art of Computer Programming*“, is his most acclaimed work. The first volume was published in 1968, and this particular edition is the 42nd print. The science and technology magazine, American Scientist, put the collected volumes on its list of books that shaped science during the last century in 2013. Additionally, he contributed to creating the Knuth-Bendix algorithm for word problems, a term for mathematical equality.^{1,2,3 }

Knuth was born in Milwaukee, Wisconsin, on January 10, 1938. When computer programming was still in its infancy in the middle of the past century, a confectionery company held a competition that called upon his skills as a 13-year-old. Kids were tasked with counting the number of words that could be formed using the letters in the candy’s name, Ziegler’s Giant Bar. It was the kind of problem he loved: well-defined, with identifiable elements. He even took two weeks off from school by convincing his parents that he was sick so that he could concentrate on the problem. Using a dictionary, he generated 4,500 words and won the competition, while the judges could only come up with 2,500 words.^{1,3}

He was initially drawn to the structure of English grammar and music, but by high school, he had developed an interest in math and physics. In 1958, Knuth created a computer program to analyze the performance of the college basketball team using his expanding expertise in programming. It generated some media attention, and IBM used a picture of Knuth in their marketing. He also examined sample programs for the school’s decimal IBM 650 mainframe and, after spotting several shortcomings, reworked the software as well as the course material. “*The Potrzebie System of Weights and Measures,*” which Dr. Knuth wrote at the age of 19, was published in Mad magazine.^{3,4,5}

Knuth graduated with a bachelor’s degree in math from Cleveland, Ohio’s Case Institute of Technology (now Case Western Reserve University) in 1960. Publishing a math article while being a PhD student is an impressive feat, yet Knuth managed to publish two papers, “*An imaginary number system*” and “*On methods of constructing sets of mutually orthogonal Latin squares using a computer* *I*” in the same year (1963) he graduated from college. As a result of Knuth’s excellence in math at Case, he was granted a Master’s degree along with his bachelor’s degree.^{3,6}

The California Institute of Technology in Pasadena, California, where he worked as an assistant and later as an associate professor from 1963 to 1968, awarded him a doctorate in math there in 1963 for his thesis “*Finite semifields and projective planes*.” He was contacted by a publisher to create a book about compilers, but it turned into a book that compiled all of his knowledge about writing for computers—a book about algorithms. Knuth produced compilers for several computers and worked as a private consultant while pursuing his mathematics Ph.D. at the California Institute of Technology.^{3,5}

Knuth, who helped establish and systematize formal mathematical techniques for the thorough investigation of the computational complexity of algorithms, has been named the “father” of algorithm analysis.^{ }^{7} In the process, he popularized asymptotic notation. He also contributed enormously to a number of theoretical computer science disciplines. A prolific author and academic, Knuth developed the MMIX instruction set architecture and the WEB/CWEB computer programming platforms intended to promote and enable literate programming.^{7,8,9}

Knuth has won a number of honors and awards, including the A.M. Turing Award (1974), the National Medal of Science (1979), and the Kyoto Prize (1996).^{7,8}^{ }
