His sculptures often focused on the essence of form, using materials like marble, bronze, and wood to create elegant, streamlined shapes. Brancusi's most famous works include Bird in Space and The Kiss, which reflect his interest in the relationship between form and space. He is considered a key figure in the modernist movement, influencing many artists and shaping the direction of 20th-century sculpture.
