I have to do this biographical case study that will take 60% of the total mark for a leadership course.

So, I need to hear what you guys think.. who do you see as an outstanding BUSINESS leader. Someone who made a huge change! A real change in any business industry (technology, food, fashion, cars, oil,..) it doesn’t really matter.. as long as s/he’s well known in the business field so that it will be easy for me to find many online information from different sources. - this is the most important thing when it comes to a 3500 words case study.

Please no ‘Bill Gates’ suggestions. Half of the students if not more will chose him!

S/He doesn’t have to be successful, it can be about someone who was considered a leader though s/he was a real failure (this will give me the ability to do a critical analysis).

Thanks!
