German chemist and apothecary who was educated by Klaproth, collaborated with him in his researches, and verified all his analyses before publication. Rose demonstrated the presence of chromium in a species of serpentine. He was the father of Heinrich Rose, the chemist, and Gustav Rose, the mineralogist. His father, Valentin Rose the Elder, was the discoverer of the low-melting alloy, Rose s metal. 

In 1770 he became an assistant to the famous chemist, Valentin Rose, who, however, died only a few months later. Although Klaproth was only twenty-seven years old when this emergency arose, he met all the responsibilities of his new position. He not only carried on Rose s duties for nine years, but acted as a father to his two fatherless sons, providing carefully for their education. The younger boy unfortunately died in childhood, but the older one, Valentin Rose the Younger, shared Klaproth s love for nature, and collaborated with him in many researches. It was Rose s task to repeat and verify all Klaproth s experiments before the... 

The Rose Pharmacy in Berlin. Valentin Rose the Elder (1735-1771), his son Valentin Rose the Younger (1762-1807), and his grandson Heinrich Rose (1795-1864) all rendered distinguished service to chemistry and pharmacy. 

Heinrich Rose, 1795-1864. German analytical chemist and pharmacist. Son of Valentin Rose the Younger. His comparative study of American columbite and Bavarian tantalite proved that columbium (niobium) and tantalum are two distinct metals. 

In 1809 Dr. Wollaston analyzed both columbite and tantalite (10). His conclusion that niobium and tantalum are identical was accepted by chemists until 1846, when Heinrich Rose (a grandson of Valentin Rose the Elder and son of the Rose whom Klaproth educated) questioned it. Rose had made a thorough study of the columbites and tantalites from America and from Bodenmais, Bavaria, and had extracted from them... 

A Latin manuscript preserved in Liittich has been published by Valentin Rose.44 This is an early fourteenth century copy of a version edited with elaboration and additions by a Spanisli-Arabian writer probably not earlier than the twelfth century.4 The content of this work is naturally quite different from that of the laboratory manuals above described. It is a catalogue of minerals and precious stones, with a summary of their more obvious physical properties, their virtues—medicinal, or occult—for the ancient habit of assigning mystical and supernatural properties to all kinds of materials in nature—so well illustrated in Pliny s records—was well maintained in Arabian natural science, as it was by the early Greek alchemists. Though... 

He also enjoyed the tutelage of Rose s children, one of whom, Valentin Rose Jr. (1762-1807), became a well-known apothecary-chemist. 

When Lavoisier reformed chemistry in France, his work was being introduced in Germany by Martin Heinrich Klaproth (1743-1817). Trained as an apothecary, Klaproth taught himself the new chemical philosophy and became an assistant to Valentin Rose (1736-1771), one of the leading chemists of the day. He became director of Rose s pharmaceutical laboratory after Rose s death. Klaproth was an extremely good and extremely exact chemist, and a significant part of his work was directed at analytical chemistry, particularly the determination of characteristics of unknown compounds. During his years as director, he discovered or verified the discovery of zirconium, uranium, tellurium, and titanium.

In the developed world, especially in North America, Western Europe, and Japan, we love to buy cut flowers for our homes, work places, as gifts or for special occasions. Over 50 million roses are given worldwide on Valentine s Day alone. Many of these cut flowers are transported long distances by air to reach the flower markets as swiftly as possible, and contribute to the problem of increased carbon dioxide emissions. 

Johann Valentin Andrea, who organized the Christian Unions, is also considered the most likely author of the Rosiemeian manifesto Christian Rosencranz. He adopted armorial bearings of a St. Andrew s cross with four roses. 

Heinrich Rose (Berlin 6 August 1795-27 January 1864), a son of Valentin Rose junr. (see Vol. Ill, p. 659), was first a pharmacist in Danzig, then in 1815 (with his brother Gustav) went to Paris with the Prussian army and became acquainted with Berthollet, Biot, Vauquelin, and Gay-Lussac. He returned to Berlin in 1816, but soon took up a pharmaceutical post in Mitau, where he was acquainted with Grotthuss. In 1819 he went to work with Berzelius in Stockholm on titanium he obtained a doctorate in Kiel in 1821 with a dissertation on its compounds with oxygen and sulphur. In 1822 he became Privat-docent in Berlin, where he had a small laboratory in 1823 he became associate professor and in 1835 professor of chemistry. (Mitscherlich was also professor in Berlin, and their relations were not satisfactory.) ... 

Valentine s Day [8]. As Valentine s Day approaches, I rush out to buy roses. Fortunately, this time, for 50 1 get 5 more roses than before. Indeed, the price of a dozen roses fell 10. How much was a rose originally worth ...

Martin Heinrich Klaproth (Wernigerode, Harz, i December 1743-Berlin, I January 1817) was from 1759 an apothecary in Quedlinburg. He began to study chemistry from books at Hannover (1766-8) and continued in Berlin (1768-70), where he was assistant in the pharmacy of Valentin Rose, the discoverer of Rose s fusible metal. On the death of Rose, Klaproth took over the pharmacy and educated Rose s two sons, one of whom, Valentin Rose junr., became a chemist of note and collaborated with him.

Wood s metal consists of bismuth, lead, tin and cadmium. It has a melting range between 50 and 80°C. Rose s metal, an alloy of bismuth, lead and tin, melts at about 100°C. It takes its name from the German chemist and pharmacist Valentin Rose Sr. (1736-1771). Tin is used as one component in bdl metal, a type of bronze. The use of tin in ornaments and household articles has been treated above in connection with tin in history.
