January 1, 1817 - Death of Martin Klaproth, discoverer of uranium, zirconium, titanium, tellurium, strontium, cerium and chromium

Pharmacist and chemist who, during his time as a professor, wrote and published a dictionary of chemistry.

He is considered the leading chemist of his time in Germany because he did much to improve and systematise the processes of analytical chemistry and mineralogy. His appreciation of quantitative methods led him to become one of the earliest followers of Antoine Lavoisier's doctrines outside France.

He discovered uranium, zirconium, and titanium and characterised them as different elements. Although he did not obtain these elements in a pure metallic state, he clarified the composition of the substances hitherto known, including the compounds of the then-known: tellurium, strontium, cerium, and chromium.
