Like his brother, the more famous landscape painter Károly Markó the Younger (Carlo Marko), he was active in Florence, Italy.
Andrea was prolific, painting landscapes in oil of diverse parts of Europe, though mostly Italy and Russia.
The works of Andrea, his brother Carlo, and Serafino De Tivoli depicting the rural landscapes around Siena, in a Macchiaioli style, gave impetus to the Scuola di Staggia [it],[2] that also loosely included painters such as Emilio Donnini (1809-1896), Carlo Ademollo, Lorenzo Gelati, Francesco Saverio Altamura, and Alessandro La Volpe [it].
[3] Among his works: I cavallari maremmani, awarded a prize at the Exhibition of Florence del 1860; Veduta delle Cave di Carrara, awarded a medal at the International Exposition of Vienna in 1873; Paese alpestre; Una vallata; Una carovana di Samoyedi; Boscaglia; Una nevicata in Russia; Le rovine di Taormina; Paesaggi italiani.
He was named professor of the Academies of Florence, Urbino, Milan e of the Società degli acquarellisti di Brussels.
