  Let $X$ be a Banach space with a separable dual. We prove that $X$ embeds
isomorphically into a $\cL_\infty$ space $Z$ whose dual is isomorphic to
$\ell_1$. If, moreover, $U$ is a space so that $U$ and $X$ are totally
incomparable, then we construct such a $Z$, so that $Z$ and $U$ are totally
incomparable. If $X$ is separable and reflexive, we show that $Z$ can be made
to be somewhat reflexive.
