The war broke out, and for a number of years I lived in darkness, with the memory of the lakes, the trees and the skies of Sweden, until I returned in 1946 to spend two unforgettable years in the laboratory of Hugo Theorell.

Due to these various circumstances, when I entered the Catholic University of Louvain in 1934, I had already travelled in a number of European countries and spoke four languages fairly fluently. This turned out to be a valuable asset in my subsequent career as a scientist.

Although attracted by the humanities, I had chosen medicine as a career, seduced by the image of the 'man in white' dispensing care and solace to the suffering. But science was lurking around the corner, in the form of an unpaid student assistantship in the laboratory of physiology.

Our investigations were very fruitful. They led to the discovery of a new cell part, the lysosome, which received its name in 1955, and later of yet another organelle, the peroxisome.

Alternative therapists don't kill many people, but they do make a great teaching tool for the basics of evidence-based medicine, because their efforts to distort science are so extreme.

We are going to completely change what it means to do advanced analytics with our data solutions. We have machine-learning stuff that is about really bringing advanced analytics and statistical machine learning into data-science departments everywhere.

The world changes materially. Science makes advances in technology and understanding. But the world of humanity doesn't change.

I like fantasy. I like horror, science fiction because I can get avant-garde with those performances in those movies.
