His father died when he was only four, forcing him to earn a living in a steel mill from an early age.
He developed his own abilities in the 1940s, soon to be influenced by the lyrical abstract imagery of the Paris School after he went to the 1947 exhibition of French art in Luxembourg City.
[2][3] Kirscht first exhibited at the Cercle artistique de Luxembourg in 1947 where he met Joseph-Emile Muller who, together with other Luxembourg painters, encouraged him to exhibit at the 1950 Salon de la Nouvelle Equipe in Esch-sur-Alzette and the 1954 Salon des Iconomaques.
[3] Although Kirscht turned to abstract painting in the 1950s with works such as Composition and Automnal, it was not until the early 1960s when he substituted acrylics for oils that he truly mastered the style.
One of his most notable works, Village (1959), makes use of geometrical forms to represent the internal lines and structures of the topic.
