Gaudin Hamiltonians generate the Bethe algebra of a tensor power of the vector representation of $\frak{gl}_N$

It is shown that the Gaudin Hamiltonians $H_1,\dots,H_n$ generate the Bethe algebra of the $n$-fold tensor power of the vector representation of $\frak{gl}_N$. Surprisingly, the formula for the generators of the Bethe algebra in terms of the Gaudin Hamiltonians does not depend on $N$. Moreover, this formula coincides with Wilson's formula for the stationary Baker–Akhiezer function on the adelic Grassmannian.
