Arthur Dehon Little !!!!

He was an american chemist who we can say revolutionized the term " Chemical Engineering " , cause he was the person to introduce the term " UNIT OPERATIONS " and categorize it into a seperate field under Chemical Engineering !!! This in turn promoted the industrial sense of research in this field . 

From the prestigious Massachusetts Institute Of Technology , at which he studied chemistry from 1881 to 1884 , he gave back his alma matter a sense of rejoice as he was the instrumental person in the development of the branch of Chemical Engineering at MIT . 


He was the co-founder and head of a student magazine called " THE TECH " . 


His notable achievement being the discovery of ACETATE . Also he obtained a patent for his devised , more effective paper processing technology plant technology .


He founded the ARTHUR.D.LITTLE ( ADL ) , an international management consulting firm , which is now a multi-national organisation which plays key roles in the development of unit operations research . 


In chemical engineering , the Unit Operation is the basic step for starting any process , thus , Arthur D Little has simply laid an effective and basic foundation for the development of this very field !!!
