History of the world is made by people. People stay here for a brief period of time. Some people leave their names behind. Probably the oldest of them all is Adam as in Adam's apple.
There are many terms which include the names of people who were associated with that either in a positive or negative way.
English words named after people are called Eponyms. The famous examples are
Boycott (after Charles Boycott)
Sandwich(after John Montagu, the 4th Earl of Sandwich, who invented it)
Decibel(after Alexander Graham bell)
In Project Management too, there are many terms which have names in them. We use those terms but we don't care to know how they looked like. Those are the pioneers of the field who gave their life time for the betterment of the art (or science).
Let us see (pun intended) few of the pioneers of the Project Management who contributed to the different knowledge areas.
