Alan Jay Perlis was an American mathematician and computer scientist, and the first recipient of the A.M. Turing Award. He played a key role in establishing computer science as an academic field, and was instrumental in developing advanced programming techniques and compiler construction. Perlis was the head of several computer science departments, and his work contributed to the development of ALGOL, the precursor to Pascal. He was also known for his philosophical approach to computer programming, which he captured in his "Epigrams on Programming".

Robert Metcalfe is a computer engineer and entrepreneur who played a significant role in the development of Ethernet. While working at Xerox in the 1970s, he was tasked with creating a networking system for the company's personal computers, which led to the invention of Ethernet. Metcalfe later founded 3Com and worked to promote the use of personal computers and local area networks. He also formulated Metcalfe's Law, which states that the value of a network increases as the square of the number of nodes in the network.

Yukihiro Matsumoto, also known as Matz, is a Japanese computer scientist and software programmer who created the Ruby programming language by blending parts of his favorite languages, including Perl, Smalltalk, Eiffel, Ada, and Lisp. Matsumoto's aim was to make Ruby a natural and balanced language that mirrored life. Since its public release in 1995, Ruby has grown to become a highly popular and influential programming language, with a devoted community of developers worldwide. Matsumoto's vision for Ruby has contributed to its success, making it simple in appearance yet complex inside.

Claude Shannon was an American mathematician, electrical engineer, computer scientist and cryptographer known as the “father of information theory”. He laid the theoretical foundations for digital circuits and information theory. His most influential work was “A Mathematical Theory of Communication” (1948), which introduced the concept of entropy as a measure of information content and established the fundamental principles of information theory .
