Maker Birthdays: Dmitri Mendeleev

Born on this date in 1834 in the small village of Aremzyani, in what was then considered Siberia, Dmitri Ivanovich Mendeleev (Wikipedia) would go on, in 1869, to publish the first periodic table of the chemical elements. Mendeleev used the periodicity he’d observed in the properties of then-known elements to accurately predict many of the properties of germanium, gallium, and scandium, which had not yet been discovered. Mendeleev died in St. Petersburg in 1907, at the age of 72. Element number 101 is named mendelevium in his honor.
