With her unique work, the artist renewed sculpture in an industrial direction through elaboration. She also made it personal through the meaning her works had for her, based on experiences in her life, such as migration to a new and unknown land and the rejection she received from multiple art galleries during the nineteen thirties and forties that prevented her from showing her work.[4] Throughout her professional career, she collected a large amount of discarded materials such as metal chunks, leftover furniture, functional objects such as boxes, and building fittings such as stairway railings and walls. During the process of construction of the works, Louise Nevelson gave a new meaning to these materials by painting them with a dominant and neutral color such as black, white, or gold, according to her artistic criteria. After this process, she proceeded to join up components in her workshop with the help of her assistants, creating a prototype of collage.
