61st Anniversary of the Discovery of Mendelevium

Mendelevium, element 101, was discovered by a research team at the University of California, Berkeley, in 1955. One of the research team members, Gregory Choppin, was an alumnus of the Loyola University Department of Chemsitry and raised in New Orleans. 

The new element was named after Dmitri Mendeleev, a Russian chemist known for formulating the modern periodic table. At the height of the Cold War, this was seen by many as a bold and controversial move. According to team member Glenn T. Seaborg, "We thought it fitting that there be an element named for the Russian chemist Dmitri Mendeleev, who had developed the periodic table. In nearly all our experiments discovering transuranium elements, we'd depended on his method of predicting chemical properties based on the element's position in the table."
