Who is Leonard Bosack?

Leonard Bosack along with his 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 was awarded the Computer Entrepreneur Award in 2009 for co-founding Cisco Systems and pioneering and advancing the commercialization of routing technology and the profound changes this technology enabled in the computer industry.

He is largely responsible for pioneering the widespread commercialization of local area network technology to connect geographically disparate computers over a multiprotocol router system, which was unheard of technology at the time. In 1990, Cisco's management fired his wife Sandy Lerner, and Bosack resigned. Bosack is currently the CEO of XKL LLC, a privately funded engineering company which explores and develops optical networks for data communications.
