Andreas von Antropoff
Andreas von Antropoff (Russian: Андрей Романович Антропов) was a Russian-born German chemist and professor at Bonn University. He coined the term "neutronium" and, in 1926, proposed a widely used alternative periodic table of elements. Born August 16, 1878, in Reval (now Tallinn), he studied engineering in Riga, chemistry in Heidelberg, and earned a Doctor of Science. He taught and conducted research in Riga and Saint Petersburg, then moved to Bonn, where he became a full professor in 1924 and later dean. He married Erika Germann in 1926. Antropoff was active in politics and aligned with the Nazi regime; he hoisted the swastika at Bonn University in 1933, led the Agricultural Research Institute in 1944, and was suspended in 1945 and retired in 1948. He died June 2, 1956, in Bonn. His 1926 paper "Eine neue Form des periodischen Systems der Elemente" presented a periodic table numbered 1 to 118 and introduced Neutronium as Element zero; Linus Pauling later used his design in 1949 without credit.
