One of the founders of Cisco
Leonard Bosack along with his former wife Sandy Lerner, is a co-founder of Cisco Systems, an American-based multinational corporation that designs and sells consumer electronics, networking and communications technology and services. He is largely responsible for pioneering the widespread commercialization of local area network (LAN) technology to connect geographically disparate computers over a multiprotocol router system, which was unheard of technology at the time. Bosack is currently the CEO of XKL, a privately funded engineering company which explores and develops optical networks for data communications.
