He is the author of the multi-volume work The Art of Computer Programming. Knuth has been called the "father of the analysis of algorithms". He contributed to the development of the rigorous analysis of the computational complexity of algorithms and systematized formal mathematical techniques for it. In the process he also popularized the Big O notation/asymptotic notation. In addition to fundamental contributions in several branches of theoretical computer science, Knuth is the creator of the TeX computer typesetting system, the related METAFONT font definition language and rendering system, and the Computer Modern family of typefaces.If you enjoy these quotes, be sure to check out other famous scientists!
