Λούντβιχ Μις βαν ντερ Ρόε (Ludwig Mies van der Rohe) was a prominent German-American architect known for his modernist designs. Born in 1886, he played a key role in the development of the International Style, emphasizing simplicity and functionalism. His famous works include the Seagram Building in New York City and the Farnsworth House in Illinois. Mies believed in the principle of "less is more," which guided his architectural philosophy. He often used materials like glass and steel to create open spaces and a sense of harmony with the environment. His influence continues to shape contemporary architecture today.
