Friedel developed the Friedel-Crafts alkylation and acylation reactions with James Crafts in 1877 and attempted to make synthetic diamonds. His son Georges Friedel (1865–1933) also became a renowned mineralogist and is well-known for Friedel's Law, which is used in X-ray diffraction calculations.","2026-02-07
