Al Shugart, co-founder of Seagate Technology, died several weeks after undergoing open-heart surgery. He’s been described as honest, profane, generous and gentlemanly. (See Mercury News story.) One of the creators of the multibillion-dollar disk drive industry, Shugart was a valley business legend, also well-known for colorful antics such as running his dog, Ernest, for Congress. He embodied the valley’s stubbornly informal ways, wearing Hawaiian shirts but exhibiting a hard-work ethos.
