People know Ray Kroc = McDonald's. We know Rockefeller = Standard Oil. We know Thomas Watson = IBM.
I'm not sure how many CEOs from 100 years ago I can name, period. Most companies that old do seem to include a person's name. But I'd say Steve Jobs stands at least as likely to be remembered as Ray Kroc or Thomas Watson, and for many of the same reasons.
In 100 years when people hear Disney they will think about Walt Disney.
Why? Because it literally is "The Walt Disney Company".

Will they think of Jobs or Gates when they hear of Microsoft or Apple? It's far from certain.
How many CEO's from 100 years ago can you name that did not have their name in the company's name?
