John and Tashia Morgridge similarly were big into philanthropy long before the Giving Pledge. John Morgridge, a billionaire, became chief executive of Cisco Systems in 1988, took it public in 1990, and later served as the company?s chairman. He and his wife Tashia have been giving away bits of their wealth for 25 years, as this Cap Times article points out. During a panel discussion about the Giving Pledge at the Global Philanthropy Forum on April 14, Tashia Morgridge explained, ?We?d already been giving away a lot of our wealth and intended to give away a lot of it.? Much of the Morgridges? giving has gone to educational institutions in Wisconsin and to environmental conservation.
