Metcalfe took his first steps towards his future career when he attended the prestigious Massachusetts Institute of Technology (MIT). He graduated with two B.S degrees in Electrical Engineering and Business Management. Metcalfe went on to Harvard, earning a M.S. in Applied Mathematics in 1970 and Ph.D. in Computer Science three years later. While studying at Harvard, Metcalfe developed an interest with the Advanced Research Projects Agency Network (ARPANET) – the world’s first operating system that shaped the internet. Metcalfe’s fascination with ARPNET was so great, that he dedicated his doctoral dissertation on it. In addition to working on his dissertation, Metcalfe worked at Xerox PACS, where he made his mark as an engineer. He is probably most notable for inventing the Ethernet the local area network that makes it possible to use PCs as communication devices. Metcalfe then moved to Xerox’s system development division in 1976, where he was involved in developing the first ever PC to have a bit map screen, mouse, word processing, Ethernet plus software that make it possible to include text and graphic in the same document.
