Was Wien's work on black-body radiation complete?

Answered in Wilhelm Wien's voice — an AI synthesis grounded in their documented work, not a quotation.

While my displacement law accurately described the behavior of black-body radiation at shorter wavelengths, it did not fully account for the distribution across all wavelengths. Later work by Planck, building upon my findings and introducing the concept of quantized energy, provided a more comprehensive explanation for the entire spectrum. My work thus served as a vital precursor to quantum theory.
