George Klein

George Klein (Georg Klein; born Klein György, 28 July 1925 – 10 December 2016) was a Hungarian–Swedish microbiologist and public intellectual. Specializing in cancer research, he was professor of tumour biology at the Karolinska Institute in Stockholm from 1957 to 1992, a chair created for him, According to Nature, the department Klein founded was "international and influential", In the 1960s he and his wife, Eva Klein, "laid the foundation for modern tumour immunology".

Three of Klein's books have been translated into English: The Atheist and the Holy City (1990); Pietà (1992), a collection of essays on whether life is worth living; and Live Now (1997). He received numerous awards for his scientific work, including the Leopold Griffuel Prize in 1974, the Harvey Prize in 1975, and the Alfred P. Sloan Jr. Prize in 1979. In 1990 the Swedish Academy awarded him the Dobloug Prize for his contribution to literature.

Early life Klein was born Klein György to a Jewish family in Budapest, but as an orphan he was brought up by his grandparents in Mezőkaszony, a little village in the Carpathian Mountains of the Hungarian-speaking part, that time eastern part of Czechoslovakia, now of Ukraine. When he was five, the family moved to Budapest, Hungary, where he attended the Berzsenyi Gymnasium.

Holocaust in Hungary Klein wrote in Pietà and elsewhere about his experiences during the Holocaust as a teenager in Budapest, after the German invasion of Hungary in March 1944. Between May and July 1944, 437,000 Hungarian Jews were deported by cattle train to the Auschwitz concentration camp, to be "resettled", according to the Germans. Most were, in fact, sent to the gas chambers.

In May or June 1944, Klein was working as a junior secretary for the Jewish Council in Sip Street, Budapest, when he was shown a copy of the Vrba-Wetzler report by his boss, Dr. Zoltán Kohn. The report was an eyewitness account of what was happening in Auschwitz, including details about the gas chambers. The authors, Rudolf Vrba and Alfréd Wetzler, had escaped from the camp in April that year. They warned that most of the deportees arriving at the camp were being killed, not resettled. Decades later, he looked for Vrba, then a professor of pharmacology in Canada, to thank him, and subsequently wrote about him and his report in two essays: "The Ultimate Fear of the Traveler Returning from Hell" in Pietà (first published in Sweden in 1989), and "Confronting the Holocaust: An Eyewitness Account" (2011) in The Auschwitz Reports and the Holocaust in Hungary, edited by Randolph L. Braham and William vanden Heuvel.

Move to Sweden Karolinska Institute

When the war ended, Klein and a friend traveled to Szeged, a town 300 km from Budapest, to find out whether its university was still functioning. Budapest's university, then known as the Pázmány Péter University, was deserted. They walked part of the way and hitched rides, arriving in Szeged on 4 February 1945. The University of Szeged was still functioning, and Klein was admitted as a student. He studied medicine there for three months before continuing his studies in Budapest.

Klein worked as an instructor in histology and pathology He returned to Budapest in September 1947 and married Eva, who joined him in Stockholm in March 1948, shortly before the Hungarian People's Republic came into existence. In 1957 Klein was promoted to professor of tumor biology, a chair created for him, and he and his wife created the Department of Tumour Biology, with a donation from a Swedish charity, Riksföreningen mot cancer. Klein led the department until 1993, after which he was its research group leader. The paper showed, as Pramod K. Srivastava wrote, "that tumors could elicit protective immunity against themselves in syngenic hosts, and that such immunity was specific to the individual tumor". According to Klein's obituary in Nature, researchers at the time believed that cancers carried "a common antigen that the immune system could recognize. The Kleins and their colleagues used a chemical carcinogen to induce tumors in mice, surgically removed these and immunized the animals with irradiated cells from their tumors. Next, the group inoculated mice with viable cancer cells and demonstrated that the immune system would only reject cancerous cells if they came from the original tumor. This clarified the field: the immune system could recognize and reject cancers, in a way that was specific to each individual." He was responsible, with Henry Harris, for establishing the "phenomenon of tumour suppression ... using the technique of somatic cell hydridization".

Personal life George and Eva Klein had three children together: a son who is a mathematician, and two daughters, one of whom is a medical doctor and the other a playwright. The couple described the beginning of their careers and how they met, in an article they wrote together in 1989, "How One Thing has Led to Another". Klein died on 10 December 2016 at the age of 91.

Awards and honors Klein was the recipient of many awards and honorary doctorates for his research and literary contributions. He was a member of the American Academy of Arts and Sciences (1967), the United States National Academy of Sciences (1973), and the American Philosophical Society (1979). His awards included:
