Early years [edit]. Arrhenius was born on February 19, 1859, at Vik (also spelled Wik or Wijk), near Uppsala, Sweden, the son of Svante Gustav and Carolina Thunberg Arrhenius.oday, Arrhenius is best known for his study published in 1896, on the greenhouse effect.
The attempts to nominate Mendeleev in 1907 were again frustrated by the absolute opposition of Arrhenius. In 1907, Mendeleev died at the age of 72 in Saint Petersburg from influenza. The crater Mendeleev on the Moon, as well as element number 101, the radioactive mendelevium, are named after him.
