In 1940, William Kroll developed the Kroll process for extracting titanium, which revolutionized the metal's production for commercial use. This magnesium reduction method allowed for the efficient and cost-effective extraction of titanium from its ores, paving the way for its widespread application in aerospace, medical, and industrial fields. Kroll's innovation not only advanced materials science but also contributed to the growth of the titanium industry, making it a vital material in modern technology.

The Kroll process for titanium extraction in 1940 enabled the production of lightweight alloys, influencing modernist themes of flight and human achievement. Poets began to explore the intersection of technology and aspiration, reflecting on the possibilities of human innovation.
