It is difficult to capture the NTI STORY in a single continuous flow. Its achievements were not made in one study, by a single scientist or a team. Sometimes a task may have engaged many and taken years to complete. Other times several tasks may have run parallel. There can be several versions, depending on the view point. Whichever way recounted, the story will have shortcomings. It is possible that the enclosed one has perhaps many. Nonetheless it is a genuine effort at capturing all the nuances that have gone into the history of NTI. Readers interested in further details are encouraged to consult the Annexures and access information from the original sources preserved at the NTI.
