Abstract: Assuming the consistency of the existence of a measurable cardinal, it is consistent to have two Banach spaces, $X,Y$, where $X$ is a weak Asplund space such that $X^{*}$ (in the weak* topology) in not in Stegall's class, whereas $Y^{*}$is in Stegall's class but is not weak* fragmentable.
