  We present an algebraic structure that provides an interesting and novel link
between supersymmetry and quantum integrability. This structure underlies two
classes of models that are exactly solvable in 1-dimension and belong to the
$1/r^2 $ family of interactions. The algebra consists of the commutation
between a ``Super- Hamiltonian'', and two other operators, in a Hilbert space
that is an enlargement of the original one by introducing fermions. The
commutation relations reduce to quantal Ordered Lax equations when projected to
the original subspace, and to a statement about the ``Harmonic Lattice
Potential'' structure of the Lax operator. These in turn lead to a highly
automatic proof of the integrability of these models. In the case of the
discrete $SU(n)-1/r^2$ model, the `` Super-Hamiltonian'' is again an
$SU(m)-1/r^2$ model with a related $m$, providing an interesting hierarchy of
models.
