# Ada Lovelace · the top woman of the 1850s

*Decade of 1841–1850 — TOP WOMAN OF THE WORLD.*

## Why number one
The Notes (1843): the first algorithm ever written for a machine.

## The margin
By the rule of the board, **Ada Lovelace is exactly +50.495495% more right than number ten** — who, this decade, was **Dorothea Dix**. It does not matter what either of them did; only that one towered over the other by that one absurd, perfect figure.

## The kind of dominance — electrical
This is **electrical** dominance: invention and the machine (`#3fd0e0`).
