Summary: We generalize von Neumann's well-known trace inequality, as well as related eigenvalue inequalities
for Hermitian matrices, to Schatten-class operators between complex Hilbert spaces of infinite dimension.
To this end, we exploit some recent results on the $C$-numerical range of Schatten-class operators
. For the readers' convenience, we sketched the proof of these results in the
Appendix.
