Cisco Systems was started in December 1984 by Leonard Bosack and Sandy Lerner. The name Cisco was actually taken from the name of the city ‘San Francisco’. In 1983 both the founders were part of the Stanford Computer Department and were interested in connecting local networks to share information instantly.
They started off the wrong way by stealing the university’s multiple protocol router software. They used this software to experiment on building their own router. They were able to build exact replicas of Stanford’s already successful ‘Blue Box’ router. In July 1986 Bosack and his new collaborator Kirk Lougheed were forced to resign from Stanford on charges on copyright violation and theft.
