| His eventual discovery of this new element was the result of months of work in the laboratory on the mineral argrodite. An account of Winkler's discovery of the new element in The Discovery of the Elements (1934) makes interesting reading. You may be surprised by the crucial step that made all the difference in finding the new element when his months of previous efforts had been fruitless. |

| Quotations for Today | |
| | The psychopaths are always around. In calm times we study them, but in times of upheaval, they rule over us. |
| | In my opinion the separation of the c- and ac-stars is the most important advancement in stellar classification since the trials by Vogel and Secchi ... To neglect the c-properties in classifying stellar spectra, I think, is nearly the same thing as if a zoologist, who has detected the deciding differences between a whale and a fish, would continue classifying them together. |
| | Die Welt der chemischen Vorg�nge gleicht einer B�hne, auf welcher sich in unabl�ssiger Aufeinanderfolge Scene um Scene abspielt. Die handelnden Personen auf ihr sind die Elemente. The world of chemical reactions is like a stage, on which scene after scene is ceaselessly played. The actors on it are the elements. |

| | Ejnar Hertzsprung, born 8 Oct 1873, was a Danish astronomer who classified types of stars by relating their surface temperature (or colour) to their absolute brightness. A few years later, working with another scientist, Hertzsprung illustrated this relationship graphically in a diagram now known by both their names. It has become fundamental to the study of stellar evolution. |
| | A French chemist, born 8 Oct 1850, is best known for the principle that makes it possible to predict the effect a change of conditions (temperature, pressure, and concentration of reaction components) will have on a chemical reaction. This principle proved invaluable in the chemical industry for developing the most efficient chemical processes. |

| | Clemens Alexander Winkler (1838-1904) discovered a new element (6 Feb 1886). He had a background in managing a cobalt glassworks and then on the faculty of the Freiberg School of Mining, when he discovered the new element in the mineral argyrodite. He named it for his country. |
