Who Charles Darwin was

Charles Robert Darwin was born in Shrewsbury on 12 February 1809, the same day as Abraham Lincoln, and died at his home, Down House in Kent, in 1882. After five years as naturalist on HMS Beagle he spent two decades building the case for evolution by natural selection, published in On the Origin of Species in 1859.

Much of that work was done by letter. Darwin corresponded with naturalists, breeders and collectors all over the world, and signed thousands of letters from his study.

The story of the signature

His usual signature was “Ch. Darwin”, abbreviating Charles in the common way of the time, sometimes “C. Darwin”. It appears at the foot of letters on subjects from barnacles to earthworms, such as an 1881 letter rejecting the idea that worms could arise from germinating seeds.

His handwriting was quick, slanted and often difficult to read, and his correspondents often had trouble making it out. The Darwin Correspondence Project at Cambridge University Library has located and transcribed around 15,000 letters to and from him, which has made his hand far easier to study.

His notebooks are just as revealing. In Notebook B, begun in July 1837, he drew a small branching diagram of descent with the words “I think” written above it, now one of the most reproduced pages in science. That notebook and another went missing from Cambridge University Library and were returned anonymously in 2022, more than twenty years after they were last seen.

What makes it distinctive

“Ch.” for Charles

The first name shortened to two letters, a common nineteenth-century abbreviation.

A fast slant

Letters lean well to the right and run together, written by someone with a lot to get down.

Function over form

No flourish; the signature closes the letter and gets out of the way.

Written for the record

Thousands of signed letters make his hand one of the best-documented of any scientist.

How to give your signature a similar feel

In the signature generator Type tab, try Herr Von Muellerhoff with a Slant of about 10° for a fast, slanted, believable pen.
Abbreviate your first name to two letters with a full stop, like “Ch.” or “Wm.”, for a compact nineteenth-century signature.
Draw it at speed in the Draw tab. The pad thins strokes when you move fast, which suits a hurried, practical hand.
Keep it legible enough for others. Darwin’s correspondents struggled; a signature should be recognisable even if it is quick.
