Apple cofounder Stephen Wozniak was in his mid-20s, working for Hewlett Packard, when he and Steven Jobs began to build the first Apple computer. When their company went public in 1980, Wozniak made $135 million.

In February of 1981, Wozniak sustained serious injuries in a plane crash. After recovering, he intermittently worked at Apple, and briefly ran his own company making universal remote controls. He has become well known for his philanthropy and interest in lifelong learning. In 1990 Wozniak hired teachers to help him collaborate with the Los Gatos School District to teach computer science to middle school students in his own computer lab.
