Alexis de Tocqueville came perilously close to never existing at all. His parents, married in 1793, spent 10 of their first 18 months of matrimony in jail — arrested for the crime of being aristocrats during the height of the French revolutionary Terror. Tocqueville’s great-grandfather was guillotined in April 1794, after being forced to watch the beheadings of his daughter and grandchildren. His newlywed parents were in the queue, awaiting the same fate, but the fall of Robespierre in July meant they were spared.
