‘I write to you today with a number of requests’ – transcribing Johann Rudolf Rahn
Help us decipher correspondence for research!
Johann Rudolf Rahn (1841–1912) is considered the father of Swiss art history and historical preservation. Our inventory contains 10,000 pages of his correspondence, which we have digitised and published on e-manuscripta.ch.
Ten years after the big retrospective marking the 100th anniversary of Rahn’s death, you can now help us transcribe and edit the letters using the e-manuscripta transcription tool. At the end, we will publish your work on the online platform.
The campagne is part of the strategic initiative Citizen Science by Zentralbibliothek Zürich.
