Majerník is a major figure in Slovak modern painting. He studied at the Prague Academy under Professors Josef Loukota and Jakub Obrovský. He belonged to "Generace 1909", a group whose members focused on social and national issues. He spent a short time in Paris in the early 1930s. After graduating from the Academy, he remained in Prague permanently. Majerník's work was heavily influenced by the rise of Nazism and his own ordeal with multiple sclerosis, which gave his work a darker tone.
