Salvador Luria is appointed Professor of Microbiology at the Massachusetts Institute of Technology. In 1964 he becomes Sedgwick Professor of Biology and in 1965, non-resident Fellow at the Salk Institute for Biological Studies. In 1970 Luria is appointed Institute Professor at the Department of Biology of the M.I.T. Later in his career, Luria includes in his researches the study of mechanisms by which certain proteins, notably colicin, operate within bacterial cell membranes.

Salvador Luria becomes Research Fellow at the Institute of Radium in Paris. Here he works with Fernand Holweck and Eugène Wollman learning their statistical techniques for analysing virus growth. But in the spring of 1940 the Nazis invade France, therefore Luria escapes in the United States via Portugal.

Salvador Luria receives one third of the Nobel Prize in Physiology or Medicine along with Max Delbrück and Alfred D. Hershey "for their discoveries concerning the replication mechanism and the genetic structure of viruses".

Luria is appointed Professor of Microbiology at the University of Illinois. In 1952, working with Mary Human, an Indiana graduate student, Luria notices that certain bacteriophages grow well in specific host bacterial strains but grow poorly in other strains. This discovery of "restricted" bacteriophage growth plays a critical role on the late finding of restriction enzymes. In these years Luria becomes an outspoken political advocate.

Salvador Luria is Guggenheim Fellow at Princeton University.

Salvador Luria arrives in New York on 12th September 1940 and he americanizes his first and middle names. He shortly becomes Research Assistant in Surgical Bacteriology at Columbia University, thanks to a Rockefeller Foundation fellowship.

Luria and Delbrück prove statistically that inheritance in bacteria follows Darwinian rather than Lamarckian principles and that mutant bacteria occurring randomly can still give viral resistance without the virus being present. The discovery that natural selection affects bacteria explains, for example, how bacteria develop antibiotic resistance.

Salvador Luria enters the Medical School of the University of Turin, where he obtains his M.D. summa cum laude. Here he works for several years in the histology laboratory of Giuseppe Levi, a gifted researcher.

Salvador Luria serves his required time in the Italian army as a medical officer.

Salvador Luria enters the University of Rome, where he takes classes in radiology and where he studies with the physicist Enrico Fermi. During his stay in Rome, he is introduced to the work of physicist-turned-biologist Max Delbrück. Luria begins experimenting with bacteriophage, the viruses that attack bacteria. In 1938 Luria moves to France to escape Mussolini’s fascist policies against Jews.

Salvador Luria is appointed Instructor, then Assistant Professor, and Associate Professor of Bacteriology at Indiana University. Luria and Delbrück return to Cold Spring Harbor almost every summer during the 1940s and 1950s to collaborate and to teach. In 1945, Luria demonstrates that bacteriophages also mutate spontaneously, revealing how they overcome bacterial resistance.

Salvador Luria is Guggenheim Fellow at Vanderbilt University, Nashville, Tennessee.

Salvador Luria attends Liceo Ginnasio Massimo d’Azeglio, where he studies philosophy and literature with Augusto Monti, a well-known antifascist intellectual.

Salvador Luria dies in Lexington, Massachusetts of a heart attack at the age of 78.

Salvador Luria is born in Turin as Salvatore Edoardo Luria, the second son of a lower-middle-class Jewish family.

Salvador Luria spends the summer of 1941 together with Delbrück at the Cold Spring Harbor Laboratories, investigating the genetic and biochemical properties of bacteriophage and its host Escherichia coli.
