About this source

What it is

This is the handwritten signature of Ada Lovelace, reading "Augusta Ada Lovelace" in cursive. It comes from an autographed letter she signed, addressed to the publisher of The Westminster Magazine, and from other documents including an 1837 land title.

Why it matters

A signature is a direct, physical trace of a person's own hand. It confirms her full name and the title "Countess" she held, and shows how she presented herself formally in her correspondence and legal papers.
