Not in and of itself, though it is almost always one of several requirements. In my view the three most important of these are:
1) Very high IQ
2) Passion/Obsession with the field, and
3) Material circumstances that allow the person to spend their time focused on the field despite a high likelihood there is no money in it.
We all know people who have one, or even sometimes two, of the above, but are in no ways geniuses. Pretty obviously a high IQ is not enough. If only. And there are plenty of average people passionate about a subject but aren't able to make any significant breakthrough's in understanding. As for material circumstances, there are loads of rich guys all over who have, or could have, complete freedom in their schedules but are in no position to add to human knowledge and understanding in the way a genius would.
