Raymond NoordaBorn 19 Jun 1924; died 9 Oct 2006 at age 82.American electrical engineer, known as "the father of computer networking" because he was primarily responsible for making widespread the business use of networked personal computers (PC's). He did not invent the local area network (LAN) by which computers share files and printers through interlinked nodes. However, as chief executive of Novell Inc (1983-94), his organization and marketing turned the company's NetWare brand software into the first major PC network operating system. It linked even previously incompatible computers, whether IBM-compatible, Apple or Unix. To establish standardization in the industry, he believed in working with competitors, for which he coined the term "co-opetition."«
