Henry Ford is the latest subject of “American Experience,” which will be broadcast on PBS stations on Tuesday from 9 to 11 p.m. Other subjects include Andrew Carnegie and John D. Rockefeller.

Ford is the only one of the three who left a company with his name. Carnegie and Rockefeller are better known for philanthropic foundations, although Ford also created a foundation with his name on it.

If there’s a lesson from Ford for today’s entrepreneurs it is this: Don’t stay in charge of the company too long.
