As Gottfried Keller’s date of death is known, his work is protected for up to 70 years after his death (Art. 29 Para. 2 CopA); this means his work was protected until 1960. As the term of protection does not take the exact day of the death of the author as its point of reference, but rather the effective date of 31 December of the year of their death (Art. 32 CopA), namely 31 December 1890 in the case of Gottfried Keller, his work was protected until 31 December 1960. Therefore, Keller’s work has been in the public domain since 1 January 1961.
