Let me refine my comment, "discovery qua social recognition of discovery" does not mean being the first to see something.

We award "discoveries" to those people who own and arrange circumstances that permit "discovery" in the narrow sense.

Which grad student had the logbook was potluck. The existence of the project, the running of the project, etc. had nothing to do with the grad. students it employed.

In the narrow sense then, the Nobel Prize is not about giving the "first human" a gold star. It is about recognizing the drivers of progress in some area. The former is accidental, the latter deliberate. In some situations, esp. in early science, these were the same people (ie. the person who put all the work into creating the project was also the first-recogniser of results).

Since the victorian era, increasingly we have to distinguish between whose ambition a project was, and whose effort saw its realization -- and which individual happen to be the first to press-play on the peak-detection software.
