Characterization of Schur's property A Banach space $H$ is said to have Schur's property if weak convergence of a sequence implies converge in norm. The most famous example of such a space is $\ell^1(\mathbb N)$, while $L^1[0,1]$ does not have this property.
My question is the following:
Is there a characterization of such spaces?
Is there a list of known examples, other than examples of the type $\ell^1(X)$?
Is it true that such space are not reflexive, when they are infinite dimensional? 
 A: (Turning my comment into an answer here):
Regarding the third question: Yes, reflexive spaces with the Schur property need to be finite-dimensional. To see that, two ingredients suffice, once you notice that the Schur property can be phrased as "weakly sequentially compact sets are sequentially compact":

*You need to show that in an infinite-dimensional space $X$, the unit ball is never (sequentially) compact. This follows from Riesz's lemma, which guarantees the existence of a sequence $(x_n) \in X^{\mathbb N}$ with $|x_n - x_m| \ge \frac 12$ for $n \ne m$.

*You need to show that the unit ball in a reflexive space is weakly sequentially compact.


The proofs for both claims are elementary, unlike the Eberlein–Šmulian theorem; they can be found e.g. (in German, I'm afraid) in

A: Rosenthal's $\ell_1$ theorem (Google) says that every bounded sequence in a Banach space contains a subsequence that is either weakly Cauchy or is equivalent to the unit vector basis of $\ell_1$.  From this you get that a Banach space has the Schur property iff for every $\epsilon > 0$, every $\epsilon$ separated bounded sequence has a subsequence that is equivalent to the unit vector basis of $\ell_1$. That answers your first question.  
The answer to the third question is, obviously, yes.  Unit balls of reflexive spaces are weakly sequentially compact by the Eberlein-Smulian theorem.  
As for the second question, there are many examples, but because of the characterization above, all are in some sense constructed from $\ell_1$.  What are you looking for?
