Feature for Today
Thumbnail of Rudolf von Kölliker

On 6 July 1817, Rudolph von Kölliker was born, one of the founders of embryology. With pioneering microscopic work on tissues, he identified the cell structure of tissues, that nerve fibres are elongated cells, and the cellular form of the egg and sperm. He also suspected that the cell nucleus was involved in heredity, but it was for others who came later to unravel that mystery. For much more background, read his obituary in the British Medical Journal, Rudolph Albert von Kölliker from 1905.


Book of the Day
The Private Science of Louis Pasteur (Princeton Legacy Library)

On 6 Jul 1885, French scientist Louis Pasteur and his colleagues began a series of injections to save a 9-year-old boy from a dreaded disease. Pasteur, a French chemist and a founder of microbiology, prepared important vaccines for several diseases. Today's book pick is: The Private Science of Louis Pasteur (Princeton Legacy Library), by Gerald L. Geison, a Princeton University history professor. In giving Pasteur the close scrutiny his achievements and their darker sides deserve, Geison’s book offers compelling reading for anyone interested in the social and ethical dimensions of science. Geison presents this unadorned truth after careful research from scrutinizing Pasteur’s private papers and laboratory notebooks, available only in recent years. This biography considers the complexities of science as it is actually created, instead of merely clinging to comforting and heroic myths.

It is available from Amazon, typically about New from $52.21. Used from $4.05. (As of earlier time of writing - subject to change.)


Quotations for Today
Thumbnail of Jean-Baptiste Georges Marie Bory de Saint-Vincent
Nature becomes fertile only by virtue of laws that oblige matter to organize itself into one of a number of necessarily very simple primitive forms. Because of their very simplicity, these are capable of constituting the basis for increasingly complex bodies, by the addition of organs calculated according to identical laws of possibility.
— Jean-Baptiste Georges Marie Bory de Saint-Vincent, French biologist (born 6 Jul 1778). quote icon
Thumbnail of  Antoine de Jussieu
I observed on most collected stones the imprints of innumerable plant fragments which were so different from those which are growing in the Lyonnais, in the nearby provinces, and even in the rest of France, that I felt like collecting plants in a new world… The number of these leaves, the way they separated easily, and the great variety of plants whose imprints I saw, appeared to me just as many volumes of botany representing in the same quarry the oldest library of the world.
— Antoine de Jussieu, French physician and botanist (born 6 Jul 1686). quote icon
Thumbnail of Joseph LeConte
It is true that the trees are for human use. But these are aesthetic uses as well as commercial uses—uses for the spiritual wealth of all, as well as the material wealth of some.
— Joseph LeConte, American geologist (died 6 Jul 1901). quote icon
