1879 Letters now online

In 1879, Darwin continued his research on movement in plants and researched, wrote, and published a short biography of his grandfather Erasmus Darwin as an introduction to a translation of an essay by Ernst Krause on Erasmus’s scientific work. Darwin’s son Francis spent a second summer at the Botanical Institute in Würzburg, Germany, learning the latest experimental techniques in plant physiology. In October, Darwin’s youngest son, Horace, became officially engaged to Ida Farrer, after some initial resistance from her father. The transcripts and footnotes of over 640 letters written to and from Darwin in 1879 are now online. Read more about Darwin's life in 1879 and see a full list of the letters.

Volume 28 (1880) now published

1880 opened and closed with an irksome controversy with Samuel Butler, prompted by the publication of Erasmus Darwin the previous year. Darwin became fully devoted to earthworms in the spring of the year, just after finishing the manuscript of Movement in plants, his most ambitious botanical book. Financial support for science was a recurring issue, as Darwin tried to secure a Civil List pension for Alfred Russel Wallace, and continued his aid for James Torbitt and the quest for a blight-resistant potato. Volume 28 of the Correspondence of Charles Darwin is now available. Read more about Darwin's life in 1880 in our Life in letters series.

Hunt for new letters: last chance!

Think you know of a letter to or from Darwin that we haven’t found? Let us know!

Although we already know of more than 15,000 letters that Darwin exchanged with nearly 2000 correspondents around the world, letters continue to come to light in both public and private collections, and we rely on the goodwill and support of archivists, collectors, scholars, and families around the world to make the corpus as complete as possible. The letters inform and are informed by one another, and our ability to understand the whole is increased with every letter we are able to add.
