Martin Heinrich Klaproth (1 December 1743 – 1 January 1817) was a German chemist who discovered uranium (1789), zirconium (1789), and cerium (1803).

Klaproth was born in Wernigerode. During a large portion of his life he followed the profession of an apothecary. After acting as assistant in pharmacies at Quedlinburg, Hanover, Berlin and Danzig successively he came to Berlin on the death of Valentin Rose the Elder in 1771 as manager of his business, and in 1780 he started an establishment on his own account in the same city, where from 1782 he was pharmaceutical assessor of the Ober-Collegium Medicum. In 1787 he was appointed lecturer in chemistry to the Prussian Royal Artillery, and when the university was founded in 1810 he was selected to Martin Heinrich Klaproth (1 December 1743 – 1 January 1817) was a German chemist who discovered uranium (1789), zirconium (1789), and cerium (1803).

After acting as assistant in pharmacies at Quedlinburg, Hanover, Berlin and Danzig successively he came to Berlin on the death of Valentin Rose the Elder in 1771 as manager of his business, and in 1780 he started an establishment on his own account in the same city, where from 1782 he was pharmaceutical assessor of the Ober-Collegium Medicum. In 1787 he was appointed lecturer in chemistry to the Prussian Royal Artillery, and when the university was founded in 1810 he was selected to be the professor of chemistry. He died in Berlin on New Year's Day in 1817. Klaproth was the leading chemist of his time in Germany.

An exact and conscientious worker, he did much to improve and systematize the processes of analytical chemistry and mineralogy, and his appreciation of the value of quantitative methods led him to become one of the earliest adherents of the Lavoisierian doctrines outside France. Klaproth found the element titanium in the ore rutile in 1791, believing it to be a new discovery, however, William Gregor is credited with the discovery of titanium, having found the metal in a different ore, (ilmenite), before Klaproth, although in the same year. He was the first to discover uranium while studying the mineral pitchblende. In addition, he discovered zirconium, and characterized uranium and zirconium as distinct elements, though he did not obtain any of them in the pure metallic state; and he elucidated the composition of numerous substances till then imperfectly known, including compounds of the then newly recognized elements: tellurium, strontium, cerium and chromium.

His papers, over 200 in number, were collected by himself in Beiträge zur chemischen Kenntnis der Mineralkörper (5 vols., 1795–1810) and Chemische Abhandlungen gemischten Inhalts (1815). He also published a Chemisches Wörterbuch (1807–1810), and edited a revised edition of F. A. C. Gren’s Handbuch der Chemie (1806).

Klaproth was elected a Fellow of the Royal Society in 1795 and a foreign member of the Royal Swedish Academy of Sciences in 1804.

The crater Klaproth on the Moon is named after him.

His son Julius was a famous orientalist. Memorial plate: Artist Ralf Sander ...more

Quotes by Martin Heinrich Klaproth (?)

“[Pechblende] einer eigenthümlichen, selbstständigen metallischen Substanz bestehe. Es fallen folglich auch deren bisherige Benennungen, als: Ресhblende Eisenpecherz, hinweg, welche nun durch einen neuen ausschliessend bezeichnenden Namen zu ersetzen sind. Ich habe dazu den Namen: Uranerz (Uranium) erwählt; zu einigem Andenken, dass die chemische Ausfindung dieses neuen Metallkörpers in die Epoche der astronomischen. Entdeckung des Planeten Uranus gefallen sei.

[Pitchblende] consists of a peculiar, distinct, metallic substance. Therefore its former denominations, pitch-blende, pitch-iron-ore, &c. are no longer applicable, and must be supplied by another more appropriate name.—I have chosen that of uranite, (Uranium), as a kind of memorial, that the chemical discovery of this new metal happened in the period of the astronomical discovery of the new planet Uranus.”
― Martin Heinrich Klaproth
