Who is the leader Engineer of all other Engineer (Architect - Civil - Mechanical - Electrical) engineer ?

I think its a complicated question and should be considered broadly. 

Let it be any structure or art... The artist or architect behind the same should be given more importance. But it hould be made the same too as an artist and Civil is considered of the same importance or more by my views.Mechanical on the other hand is in every concept of development. Its been there from stone age till here.And nowadays without power we are literally in stone age. So Electrical too is of utmost importance.

All that being said, it could be concluded that there aint no leader but everyone works hand in hand to build a better tomorrow.
