My Research for Charles and Emma: The Darwins’ Leap of Faith

On this site you will find links that will help you explore in much the same way as I did to find the true Charles Darwin. It is not instead of the book, which, of course, you should buy (Indiebound, Amazon.com, Barnes and Noble) or take out of your library. But these pages and links will lead you down some interesting paths, I promise.
Start with my publisher’s web page about the book, Macmillan: Charles and Emma. There you will find a description of the book and a Teacher’s Guide with some thought-provoking questions. (I didn’t make up the Guide; but I think I know the answers…)

How I did my research. I have been to England and visited Down House. I loved to be able to walk in the rooms where Charles and Emma sat and worked. Walking into Charles’s study was amazing and walking on the Sand Walk with my husband and children was a true experience. But when it came time to write the book, I did most of my research right at my desk—with forays to the library for books and more books. I also did a lot of research online because fortunately there are many great Darwin sources on the Web. Both with books and on the internet, I relied most heavily on primary sources.
My “bibles” were:
- a two-volume set of letters collected by Charles and Emma’s daughter, Henrietta Litchfield. It’s called EMMA DARWIN: A CENTURY OF FAMILY LETTERS. I was lucky enough to be able to take it out of the library at Columbia University, where my husband is a professor. You can go to the public library, perhaps, and find it and browse on your own. Or you can go to Google Books and, because it is so old, find it there. Here is volume 1 of Emma Darwin: A Century of Family Letters and here is volume 2. How cool is that?
- The Autobiography of Charles Darwin (in various editions). Including this one.
- Charles Darwin’s Notebooks, which you can find here. Take a look at this entry. Scroll down, or search for the word “saliva.” You’ll recognize it from the book.

This page will lead you to great photographs, a timeline, as well as obituaries and memories of Darwin. Have fun! For my own idiosyncratic time line, click here.
Many of Charles’s letters, and the ones he received, you can find here at the Darwin Correspondence Project. The good people who run the project, and have for many years, are in the process of getting as many of Charles’s 12,000 (about) written or received letters in print and on line. These people there are my heroes. Charles had about 2,000 correspondents in his lifetime and his letters are a treasure trove. I used this site constantly while researching my book and found treasures such as this one: a collection they put together about Darwin’s thoughts about religion.
Here is the letter he wrote to Emma asking her to take care of the publication of his species draft “in case of my sudden death.”
There are many, many wonderful resources on the web about Darwin. In addition to the two above, you should check out these:
- The American Museum of Natural History in New York had a great exhibit on Darwin and they put it all online. Check it out here. After I finished writing CHARLES AND EMMA, I met one of the people who worked on that show, and it was like meeting a movie star. She and I sat and talked about Charles and Emma for as long as our hosts at the dinner party would let us.
- I’ve already mentioned the University of California, Berkeley’s explanation of natural selection, but if you start here you will get a great many pages and a lot of information about Understanding Evolution.
- WGBH, the great Public Television station out of Boston has a terrific web site about evolution.
- And this site, About Darwin, is terrific.
Have fun! And remember, as always, to double check any facts you want to use in a paper.
