A member of a Reformed family, he completed his studies at the School of Applied Arts and later at the Academy of Fine Arts, before furthering his education at the Scuola Libera in Rome and Florence. In 1905, he gained attention with his painting "Autumn Landscape." From 1911 to 1912, he received awards from the National Hungarian Council of Fine Arts and Landscape Painters, becoming a regular participant in their exhibitions. He began signing his works under the pseudonym Andaházy from 1912. He lived in Paris for a while, organizing several exhibitions, the last being in 1927 at the Galerie Durand-Ruel, showcasing landscapes from Brittany, Normandy, and the Côte d'Azur, as well as sketches from Paris. Some of his paintings are held in the Hungarian National Gallery and others belong to the city of Budapest. During World War I, he served as a reserve captain and was wounded twice. During the Hungarian Soviet Republic, he was part of a brigade tasked with collecting publicly owned artworks. He also received aid from the People's Commissariat for Education, which purchased one of his paintings. He began his political career as a member of the short-lived Hungarian Kingdom Party, later joining the Hungarian Workers' Party. Despite initial setbacks, he eventually entered parliament in 1921 as a member of the Hungarian Workers' Party. He was most vocal in parliament against the land reform and numerus clausus policies. He later emigrated to Paris due to his oppositional stance, returning to Hungary and aligning himself with various political parties before eventually settling in Buenos Aires, Argentina. He remained involved in Hungarian politics from afar, but his later life remains somewhat mysterious, with conflicting reports about his death. One of his grandsons, Federico Andahazi-Kasnya, became a writer.
