Bob Frankston and Dan Bricklin, inventors of the spreadsheet

MIT grads Dan Bricklin (right) and Bob Frankston developed the first electronic spreadsheet, VisiCalc, in the late 1970s. Though they were among the earliest tech pioneers, they are not as celebrated today as contemporaries such as Bill Gates and Steve Jobs, in part because their product was always better known than their company, Software Arts. But Bricklin has said he is okay with that. "In many cases, you should set up a company around a product, and the goal should be to get the most out of the product over its life span," he told Inc. in 1989. "Sometimes that may even involve ending the company at a certain point. I see lots of examples [of] products that have a limited life span -- less than 10 years, maybe even less than three years."
