# Grandpa — The Autobiography of an Idea character guide

> Grandpa in The Autobiography of an Idea by Louis H. Sullivan.

**Role:** supporting

**First appearance:** 0000-i-the-child

## Snapshot

Louis's well-traveled grandfather, a former French teacher at West Point whose casual revelations about the Hudson and his own past alternately dazzle and wound his indifferent grandson.

## Who they are

Grandpa shepherds Louis down the Hudson toward Boston, pointing out the Palisades and mentioning that he once swam the river before breakfast at the Military Academy. He feels the sting of the boy's careless ignorance about the family's own history, shuddering at the chasm between them, and grieves that Louis pays the penalty of a sheltered life. His quiet conviction that every unrecorded human life holds the key to destiny gives the early chapters their reflective, elegiac undertone.
