The Darwin Project collaborated with the Cambridge Digital Library to publish images of about 1,200 letters exchanged between Charles Darwin and Joseph Dalton Hooker. There are more than 5,000 images in the collection.
No single set of letters was more important to Darwin than those exchanged with the botanist Joseph Dalton Hooker (1817-1911). Their letters account for around 10% of Darwin’s surviving correspondence and provide a structure within which all the other letters can be explored. They are a connecting thread that spans forty years of Darwin’s mature working life from 1843 until his death in 1882, and bring into sharp focus every aspect of Darwin’s scientific work throughout that period. They illuminate the mutual friendships he and Hooker shared with other scientists, but they also provide a window of unparalleled intimacy into the personal lives of the two men.
