Gershom Scholem is celebrated as the twentieth century's most profound student of the Jewish mystical tradition; Walter Benjamin, as a master thinker whose extraordinary essays mix the revolutionary, the revelatory, and the esoteric. Scholem was a precocious teenager when he met Benjamin, who became his close friend and intellectual mentor. His account of that relationship--which was to remain crucial for both men--is both a celebration of his friend's spellbinding genius and a lament for the personal and intellectual self-destructiveness that culminated in Benjamin's suicide in 1940.
