  The Milanese period in Albert Einstein's life is a key one for the
understanding of the development of his scientific questioning. While being a
student in Z\"urich from 1896, Einstein returned regularly to Milan to meet his
family for the holidays. There, he could work on the most recent articles in
physics at the rich library of the Lombardo Institute, Academy of Sciences and
Letters. Hopefully, this new perspective will help to trace back more
accurately a few of Einstein's scientific ideas, such as the need to expand his
first doctoral work on molecular forces to weakly compressed gases or as to
conceive a first idea of light quanta.
