Origins & Early Life

Martin Heinrich Klaproth (1 December 1743 – 1 January 1817) was a German chemist. He trained and worked for much of his life as an apothecary, moving in later life to the university. His shop became the second-largest apothecary in Berlin, and the most productive artisanal chemical research center in Europe. Klaproth was a major systematizer of analytical chemistry, and an independent inventor of gravimetric analysis.

Pivotal Works & Achievements

His attention to detail and refusal to ignore discrepancies in results led to improvements in the use of apparatus. He was a major figure in understanding the composition of minerals and characterizing the elements. Klaproth discovered uranium (1789) and zirconium (1789). He was also involved in the discovery or co-discovery of titanium (1795), strontium (1793), cerium (1803), and chromium (1797) and confirmed the previous discoveries of tellurium (1798) and beryllium (1798). Klaproth was a member and director of the Berlin Academy of Sciences.

Enduring Legacy & Impact

He was recognized internationally as a member of the Royal Society in London, the Institut de France, and the Royal Swedish Academy of Sciences. Klaproth was born in Wernigerode. He was the son of a tailor...
