Foni (Alphonse) Tissen (1909–1975) was a Luxembourgish schoolteacher and artist who is remembered principally for his hyperrealistic, darkly humorous paintings, many of which were self-portraits.
After primary school in Rumelange, he attended the Lycée Poincaré in Nancy before studying painting and architecture at the Ecole des Beaux-Arts in Paris.
In September 1942, after taking part in the strike against the German occupation, he was deported together with seven other teachers to the Hinzert concentration camp where the inhuman conditions were to exert a profound influence on his work, calling for an ironic level of introspection.
While his postage stamps, posters and the logo for the emergency services have become part of Luxembourg's collective memory, his close attachment to his native Rumelange and the area's Red Rocks can be seen in his landscapes and engravings.
The most typical part of his work is however the series of paintings he referred to as his Maennerscher or little men, many of them self-portraits constituting a human one-man comedy.
