Constantin Brancusi was a renowned Romanian sculptor who pioneered modernist sculpture in the early 20th century. His sculptures blended simplicity and sophistication through abstraction to focus on the essence rather than outer form of his subjects. After studying in Romania, he moved to Paris in 1903 where he developed his unique style, rejecting realism and the techniques of his contemporaries. His iconic works like "Bird in Space" and the "Endless Column" at the World War I monument in Târgu-Jiu established his reputation and influence on modern sculpture.
