In 1891, Carlo Fornara discovers for the first time Divisionism. However, after a sojourn in Lyons, France, he adopts the more spontaneous neo-impressionist technique, as shows his picture En plein air, refused at the 1897 Triennale of Milan, for the audacity of its colours! An important step in his career is his encounter with Giovanni Segantini and Vittore Grubicy de Dragon, both famous Divisionist artists whose influence lead him to adopt the divisionist technique. He regularly shows his works in important international exhibitions. Later, he adopts a more personal style and retires in Val Vigezzo in 1922.
