Death of Friedrich Bergius (German chemist, Nobel laureate), March 30. Friedrich Bergius was a prominent German chemist born in 1884, renowned for his pioneering work in industrial chemistry. He is especially known for developing the process of hydrogenating coal to produce liquid fuels, a method that played a significant role in twentieth-century energy industries. In 1931, Bergius, together with Carl Bosch, was awarded the Nobel Prize in Chemistry for their research on high-pressure chemical reactions and their applications. Throughout his career, Bergius worked at several research institutions and industrial centers, making substantial contributions to the advancement of chemical and industrial technologies. Despite facing political and economic challenges of his era, he continued to innovate, and his achievements in converting raw materials into chemical products inspired future generations of scientists. His death on March 30, 1950, marked the end of a prolific scientific career. This observance is recorded in the Gregorian calendar as a reminder of Bergius's role in the progress of chemistry and industrial technology. Commemorations typically involve reflecting on his scientific achievements and their impact on the chemical industry. The inclusion of this date in the 1950 Gregorian calendar followed his passing and was designated to honor his contributions to science and technology.
