(July 10, 1871 - November 18, 1922)
Marcel Proust was a French writer. On January 1, 1909, he ate a piece of tea-soaked toast whose taste caused a flood of childhood memories.
In his 7 volume allegorical novel 'Remembrance of Things Past,' the character Swann has a similar experience when he bites into a lemon cookie (a madelaine) which brings on a similar flood of memories. This is one of the most widely-quoted allusions in literature.
