It is very difficult to choose the best in my field. Indeed public administration goes with a lots of other subject. One can find that a great state man is the best public administrator. In that case I would have to say that C. de Gaulle was the best one. He succeed to save and rebuild French administration after WW2 and later build a complete new administration by creating the fifth Republic.
But other think that political philosophy is the core of public administration in the way that it inspires its organization. In this sense I should support Montesquieu as the best in my area. Without a doubt his book The Spirit of Law is one of the most important. His concept of check and balances influences all the modern democratic Administrations. 
Finally, one can claim that the best in this field are those who directly work at it : Public Administrators. Here in France, I would have to choose Maurice Laure. He is not famous but assumed his charges with a great honour and has contributed to improve administration. He is the inventor of the Value added tax which allows a better efficiency and fairness for the taxpayer. This concept was expanded to a lot of other countries.
