@oristarA,
Yeah, Oris, I agree with you and Dale. If any elaboration is needed (and I don't really think there is), then I would just add this. The remainder of the passage makes this clear. It says:
Quote:Prof Ernst continued in his work despite personal attacks and attempts to undermine his research unit and end his employment. As a result, he has addressed a significant gap in the research base in this field and has brought insights into discussions...
There was a need for the research EVEN THOUGH many tried to reject that need, and even tried to get him fired. Yet he persisted, and his research has proved to be valuable.
The implication is that there are still many remaining who don't see (or refuse to acknowledge) the relevance and/or importance of this research. Therefore it is important to communicate the NEED for such research, so that more of it can/will be done by more scientists.
