    100 Distinguished European Chemists

    Celebration of 100 Distinguished European Chemists from the Chemical Revolution to the 21st Century

    The Federation of European kemikalie Societies initiated, as a Millennium Project, the celebration of Distinguished European Chemists spanning a period of over two hundred years.

    Member societies and individuals were invited to submit their nominations of distinguished European chemists from the end of the 18th century until the present day. In addition to Nobel Prize winners, there were nominations of many others from Europe who have, over more than two centuries, transformed the science and influenced science, industry or society worldwide.

    The final list includes a diversity of nationalities. As well as being published in the magazines of the national chemical societies the list is available for viewing here along with a brief biography and details of their achievements.

    February 25 marks the passing of Theodore H. E. Svedberg. Svedberg was a Swedish chemist best known for the invention of the ultracentrifuge.

    Svedberg was a colloid chemist studying the various physical properties of particles suspended in solution such as diffusion, light absorption, and sedimentation. His work helped prove Einstein’s theory of Brownian motion applied to particles in a colloid and gave the first physical evidence of the existence of molecules. In order to accomplish this, Svedberg needed to separate his colloids.

    Colloids are insoluble mixtures suspended in some other substance. Left to their own devices, many colloids will settle into layers with the heavier particles at the bottom and lighter floating on top thanks to gravity. Think of a bottle of oily salad dressing. Shake it up, herbs are distributed evenly throughout the dressing container in the oil. Let it sit for a while, you’ll find the herbs on the bottom and the oil sitting on top. The
