Executive Chairs

I am looking for a new president, and I noticed that most of the names of similar companies that use their class president. Chairman of the Group Manager President President of the computer network drafting chair where these names come from? What makes a chair very specific to a particular task. And what is a good president to work, sitting at a computer 12 hours a day? (The chairs computer seems to be on the bottom line?) The only two who were preparing for me and for the executive to do? Source Wikipedia gets the best answer, like knowing the history of this promotion / designation. Curious, who then initiated a chair pattern from a nursery. I think I'll never know.
