Who is known as the father of modern sculpture?

Constantin Brâncuși is widely recognized as the father of modern sculpture due to his influential approach that transformed traditional sculptural forms and techniques. His innovative use of materials, coupled with a focus on simplification and abstraction, led to significant developments in the field. Brâncuși's desire to capture the essence of his subjects while stripping away unnecessary details helped pave the way for modern abstraction in sculpture. Works like "Bird in Space" highlight his ability to blend organic forms with a minimalist aesthetic, emphasizing purity, integrity, and a connection to both the material and the spiritual.

In contrast, Henry Moore, Alberto Giacometti, and Amedeo Modigliani all contributed to the art world in significant ways but did not have the same foundational impact on the trajectory of modern sculpture as Brâncuși did. Their works are often viewed as extensions of the traditions that Brâncuși challenged and redefined.
