Earlier quoted context omitted.
Alfred Nobel apparently disagreed, and it's still the interest on the money bequeathed by his will that funds the prize. So it's unlikely that the name will be changed.
Neither kind of restriction is applied to the physics or chemistry prize (they do not require some sort of nebulous "medical benefit" to qualify).
I'm not talking about the medical benefit, I'm talking about the name specifically. His will stated that there should be prizes for chemistry, physics, literature, peace, and physiology or medicine.
