"Max Schneckenburger (17 February 1819 – 3 May 1849) was a German poet. The patriotic hymn "Die Wacht am Rhein" uses the text of a poem Schneckenburger wrote in 1840.
Schneckenburger was born in Talheim near Tuttlingen, Württemberg. The younger brother of Matthias Schneckenburger, he was a co-owner of an iron blast furnace company, and his business sent him across the Rhine River to Switzerland. Due to this connection, a first version of his poem was set to music and performed there in 1840 by local musicians. This Bern version is now largely forgotten. Schneckenburger died in Burgdorf near Bern." - (en.wikipedia.org 31.01.2020)
