There is an amazing slightly older longform article on the creator of supermemo (the original spaced repetition software, although the concept of course comes from a German psychology pioneer of a few centuries ago (Helmholtz i think?)).

The supermemo site also has a lot of fascinating articles written by the guy, really worth looking at if the topic interests you.
