In computing, Joy's law, first formulated by Sun Microsystems co-founder Bill Joy in 1983, states that the peak computer speed doubles each year and thus is given by a simple function of time.
 Specifically,
Charles William Bachman III (Born on December 11, 1924 – July 13, 2017) was an American computer scientist, who spent his entire career as an industrial researcher, developer, and manager rather than in academia.
 He was particularly known for his work in the early development of database management systems.
Leonard Kleinrock (born June 13, 1934) is an American computer scientist.
 A professor at UCLA's Henry Samueli School of Engineering and Applied Science, he made several important contributions to the field of computer networking, in particular to the theoretical foundations of computer networking.
 He played an influential role in the development of the ARPANET, the precursor to the Internet, at UCLA.
Chittoor V. Ramamoorthy (1926 – 2016) was an American computer scientist, computer engineer and educator whose work had many implications in engineering, computer science, and software engineering.
 Together with Raymond T. Yeh, he is given credit for the early establishment of the discipline of software engineering.
 He had a large following worldwide with whom he actively collaborated until the last few months of his life.Advances made during these collaborations included the exploration of transdisciplinary methods and the development of a science to support future complex systems design
Eugene Wimberly "Gene" Myers, Jr. (born December 31, 1953) is an American computer scientist and bioinformatician, who is best known for contributing to the early development of the NCBI's BLAST tool for sequence analysis.
Ivan Edward Sutherland (born May 16, 1938) is an American computer scientist and Internet pioneer, widely regarded as the "father of computer graphics."
 His early work in computer graphics as well as his teaching with David C. Evans in that subject at the University of Utah in the 1970s was pioneering in the field.
 Sutherland, Evans, and his students from that era invented several foundations of modern computer graphics.
 He received the Turing Award from the Association for Computing Machinery in 1988 for the invention of Sketchpad, an early predecessor to the sort of graphical user interface that has become ubiquitous in personal computers.
 He is a member of the National Academy of Engineering, as well as the National Academy of Sciences among many other major awards.
 In 2012 he was awarded the Kyoto Prize in Advanced Technology for "pioneering achievements in the development of computer graphics and interactive interfaces".
William Nelson Joy (born November 8, 1954) is an American computer scientist.
 He co-founded Sun Microsystems in 1982 along with Vinod Khosla, Scott McNealy and Andreas von Bechtolsheim, and served as chief scientist at the company until 2003.
 He played an integral role in the early development of BSD UNIX while a graduate student at Berkeley, and he is the original author of the vi text editor.
 He also wrote the 2000 essay "Why the Future Doesn't Need Us", in which he expressed deep concerns over the development of modern technologies.
Peter Shirley (born 1963) is American computer scientist and computer graphics researcher.
 He is a Distinguished Scientist at NVIDIA and adjunct professor at the University of Utah in computer science.
 He has made extensive contributions to interactive photorealistic rendering.
 His textbook, "Fundamentals of Computer Graphics", is considered one of the leading introductory texts on computer graphics and is currently in the fourth edition.
John McCarthy (September 4, 1927 – October 24, 2011) was an American computer scientist and cognitive scientist.
 McCarthy was one of the founders of the discipline of artificial intelligence.
 He coined the term "artificial intelligence" (AI), developed the Lisp programming language family, significantly influenced the design of the ALGOL programming language, popularized timesharing, and was very influential in the early development of AI.
Juan E. Gilbert (born February 27, 1969) is an American computer scientist, researcher, inventor, and educator.
 A staunch advocate of diversity in the computing sciences, Gilbert's successful efforts to increase the number of underrepresented minorities in the computing disciplines have been recognized by professional engineering organizations and the United States government.
 In honor of both his accomplishments and his service to the university, Gilbert was awarded the first Presidential Endowed Chair at Clemson University on November 9, 2012.
 As a result of Dr. Gilbert's efforts, in 2012, Clemson was home to 10% of the African American computer science professors, and 10% of the African American computer science doctoral students in the United States.
 In 2014, Dr. Gilbert left Clemson University and joined the Computer & Information Science & Engineering Department at the University of Florida where he serves as the Andrew Banks Family Preeminence Endowed Chair and the Chair of the department.
 Dr. Gilbert is the first African American chair of the Department of Computer & Information Science & Engineering at the University of Florida.
