An annual survey of CEOs returns this list:

1. Winston Churchill
2. Steve Jobs
3. Mahatma Gandhi
4. Nelson Mandela
5. Jack Welch
6. Abraham Lincoln
7. Margaret Thatcher
8. Ronald Reagan
9. John F. Kennedy
10. Napoleon Bonaparte

All conventional and safe, of course, the traditional boilerplate we would expect from CEOs — and, as we should also expect, seven of the ten are former heads of state.
