XVich stores of the rare earth minerals lay hidden for centuries m the Scandinavian peninsula until, one day in 1787, Lieutenant Carl Axel Arrhenius found, near the Ytterby feldspar quarry in Roslagen, an unusual black rock which he at first called ytterite, but which was later named gadolinite for the famous Finnish scientist Johan Gadolin who detected in it yttria, scandia, and all the rare earths of the yttria group. 

Carl Axel Arrhenius, 1757-1824. Swedish chemist and mineralogist. In 1787 he discovered in the Ytterby quarry a new black rock which he named ytterbite. In 1794 Gadolin discovered the complex earth yttna in this mineral, which has since been renamed gadolinite...

In 1787, Carl Axel Arrhenius (1757—1824), a Swedish army officer and amateur mineralogist, found a rock in a mine at Ytterby, a region near Stockholm. He named the rock ytterite. A few years later, the rock was analyzed by Johan Gadolin (1760—1852), a professor of chemistry at the... 

The discovery of the lanthanoids began outside the small town of Ytterby, Sweden, in 1787. A Swedish army officer named Carl Axel Arrhenius (1757—1824) found an unusual kind of black mineral in a rock quarry. That mineral was later given the name gadolinite. 

In 1787, a lieutenant in the Swedish army named Carl Axel Arrhenius (1757-1824) was exploring a mine near Ytterby, Sweden. Arrhenius was a rock hound, a person interested in the study of rocks and minerals. In his explorations, Arrhenius found a rock he had never seen before. He... 

In 1787, a Swedish army officer named Carl Axel Arrhenius (1757— 1824) found a strange looking black rock outside the town of Ytterby, Sweden. He passed it along to Johan Gadolin (1760-1852), professor of chemistry at the University of Abo in Finland. Gadolin discovered a new mineral in the rock, now known as yttria. 

In 1878, French chemist Jean-Charles-Galissard de Marignac reported his analysis of the mineral erbia. Erbia was one of the minerals found a century earlier in an interesting new rock called yttria. The rock had been discovered outside the town of Ytterby, Sweden, in 1787 by Swedish army officer Carl Axel Arrhenius (1757—1824). In the century that followed Arrhenius discovery, chemists worked hard to find out what elements were in yttria. Earlier chemists thought erbia was a new element, but Marignac disagreed. He said that erbia consisted of two new elements, which he called erbium and ytterbium. 

In 1787, a lieutenant in the Swedish army named Carl Axel Arrhenius (1757—1824) found an interesting new stone near Ytterby. He gave the stone to Johan Gadolin for analysis. At the time, Gadolin was professor of chemistry at the University of Abo in Finland. Gadolin decided that Arrhenius rock contained a new element. That element was later given the name yttrium. 

Carl Axel Arrhenius found in 1787 in a quarry near Ytterby, Sweden, a new mineral, which he named ytterbite, and made a summary analysis of it. Further, the Finnish chemist Johan Gadolin isolated in 1794 from this mineral an impure new oxide that he named ytterbia. Friedrich Wohler partly purified the metal yttrium in 1828, whereas Carl Gustaf Mosander separated the oxides of yttrium, erbium and terbium in 1843 from a mixture of yttria oxide. 

Carl Axel Arrhenius (1757-1824) did not care much for the military profession (he was an officer of the engineer corps), but was passionately interested in chemistry and mineralogy. He frequently visited the laboratory of the Mining Academy. During his stay in Paris he attended the lectures of Lavoisier and Fouicroy. He was one of the first champions in Sweden of the new antiphlogistic chemistry based on oxygen. When in Sweden, he attended the lectures of Berzelius and also worked in his laboratory. He terminated his military career as lieutenant-colonel, but parallelly he also made a remarkable scientific careen he was elected a member of the Swedish Academy of Science (Anonymous 1824).

As part of the world-wide celebration of the 200th anniversary of the discovery of the rare earths by Lieutenant Carl Axel Arrhenius, the editors and publishers of this Handbook series are pleased to dedicate this volume to the scientists, engineers, technologists, industrialists, and others who have contributed to discoveries, advancements, knowledge and applications of these materials since 1787, and have brought the rare earths to their imposing present-day position.
