Like Herbert Fisk Johnson III, 23 percent of the billionaires who have emerged from Cornell inherited their fortunes, rather than made them on their own (or spun an inheritance into greater wealth). "Fisk" is the fifth of his line to head up the cleaning products giant SC Johnson & Son. Not that he couldn't have succeeded on his own: he has two master's degrees, in engineering and physics, as well as a Ph.D. in physics and an MBA, all earned at Cornell University and its graduate school of management, named after his great-great-grandfather, Samuel Curtis Johnson, founder of the company.
