F. W. Taylor and P. White present the first molybdenum-based high-speed steels at the Exposition Universelle in Paris in 1900.

Simultaneous with the presentation by the two American engineers, chemists Marie Curie in France and J. A. Mathews in the United States use molybdenum to prepare permanent magnets.

Tungsten is brought to public attention in 1900 by the Bethlehem Steel Company with its tungsten-containing high-speed tool steel products at the Exposition.
