Roberto Todeschini

The concept of molecular structure is one the most important concepts in the development of the scientific knowledge of the XX century. As a matter of fact the reasoning based on the molecular structure has been the main engine for the great development of physical chemistry, molecular physics, organic chemistry, quantum chemistry, chemical synthesis, polymer chemistry, medicinal chemistry, etc...

Carl Djerassi (1923–2015)

Few lives at the top of chemistry and industrial accomplishments in the 20th century have been as remarkable as that of Carl Djerassi, who died in San Francisco on January 30 at the age of 91. To a considerable extent, his life became known as ‘fascinating’, catalyzed by his own portrayal of it. This feature of his persona cannot, and will not, dilute the one major scientifi c contribution he m...
