Final answer:
The two significant documents found after a person's death are often the Last Will and Testament and the Heiligenstadt Testament, the latter being specific to Ludwig van Beethoven. They highlight the individual's personal desires and, in Beethoven's case, his inner turmoil and dedication to art.
Step-by-step explanation:
The two significant documents found after the subject's death are likely his Last Will and Testament and the Heiligenstadt Testament. The Last Will and Testament is a standard document that outlines a person's desires for how their estate should be handled after their passing.
The Heiligenstadt Testament, however, refers to a specific document written by Ludwig van Beethoven in 1802 in which he expressed his despair over his increasing deafness and his resolve to continue living for and through his art. While not specifically related to the snippets provided, these two documents often hold great significance when discussing the posthumous discovery of personal documents of historical figures.
