Giacomo Ciamician (1857-1922) was a pioneer in the study of photochemical reactions and their applications. However, at the time, the light sources in the scientific laboratories were too weak to conduct meaningful experiments. He therefore had to use sunlight for his researches. To this end, he used a terrace of the Institute of Science of the University of Bologna. In this picture, dating from the first decade of the 20th century, he inspects the flasks that contained the organic substances whose light induced transformations he wanted to study together with his friend and collaborator Paul Silber (1851-1932).
Serradella, alfalfa and sand vetches are just a few examples of forage crops that have left their mark in the archives of Amaat Dumon, professor of agricultural sciences. As head of the Breeding Station of the Belgian Farmers' Union, of the university Laboratory for Applied Genetics and of the Flemish department of the General Inspection Service for Seeds and Seeds, Dumon was an expert in the extraction, propagation and breeding of seeds. His remarkable didactic collection includes dozens of test tubes, sachets and aspirin tubes filled with colorful seeds.
