He was raised with simplicity but received an exceptional education towards shaping what Brazilians then considered an ideal ruler. The sudden and traumatic loss of his parents, coupled with a lonely and unhappy upbringing, greatly affected Pedro II and shaped his character.

Document 9: John von Neumann: Additionally, "[I]n the general case, von Neumann proved the following basic representation theorem. Any complemented modular lattice L having a "basis" of n≥4 pairwise perspective elements, is isomorphic with the lattice ℛ(R) of all principal right-ideals of a suitable regular ring R. This conclusion is the culmination of 140 pages of brilliant and incisive algebra involving entirely novel axioms. Anyone wishing to get an unforgettable impression of the razor edge of von Neumann's mind, need merely try to pursue this chain of exact reasoning for himself—realizing that often five pages of it were written down before breakfast, seated at a living room writing-table in a bathrobe."
