Eligio Perucca (28 March 1890 in Potenza – 5 January 1965 in Rome) was an Italian physics instructor and researcher at the University of Turin in Italy in the early decades of the twentieth century. He later served a professorship at the nearby Polytechnic University of Turin. He discovered an important principle in stereochemistry in 1919, but his contribution was overlooked and forgotten until recently.
Donato Bilancia (10 July 1951 – 17 December 2020) was an Italian serial killer who murdered seventeen people – nine women and eight men – on the Italian Riviera in the period from October 1997 to April 1998.Bilancia's inconsistent modus operandi made him difficult to identify and capture. There were no obvious links between the majority of his murders. He chose most of his victims at random, across a vast area of Northern Italy, and became a synonym for fear among the people living along the Italian Riviera. He was given the nicknames Mostro della Liguria ("The Liguria Monster") and L'assassino dei treni ("Killer on the trains").
Initially attributed with only nine homicides by the Italian police, Bilancia later confessed to having killed eight other people. With a sentence to 13 terms of life imprisonment, and no possibility of release, Bilancia has been defined by some newspapers as "the worst serial killer in the history of Italy". Despite confessing to the killings, Bilancia never explicitly regretted his crimes, claiming that he did not consciously commit them because he was "possessed" by a disease. Bilancia died on 17 December 2020, in prison, from COVID-19.
