Background.
Kauppi married a woman named Liina Lovisa Lindström in 1908.
He wrote two operas. The first, in 1925, was "Päiväkummun pidot" (The Feast at Solhaug), which was well received by critics. The second, in 1930, was "Nummisuutarit" (The Cobblers on the Heath), which received only poor reviews.
