André Michel Lwoff (8 May 1902 – 30 September 1994) was a French microbiologist and Nobel laureate of Russian-Polish origin.

Louis Ferdinand Auguste Destouches (27 May 1894 – 1 July 1961), better known by the pen name Louis-Ferdinand Céline ( say-LEEN, French: [lwi fɛʁdinɑ̃ selin] ), was a French novelist, polemicist, and physician. His first novel Journey to the End of the Night (1932) won the Prix Renaudot but divided critics due to the author's pessimistic depiction of the human condition and his writing style based on working-class speech. In subsequent novels such as Death on the Installment Plan (1936), Guignol's Band (1944) and Castle to Castle (1957) Céline further developed an innovative and distinctive literary style. Maurice Nadeau wrote: "What Joyce did for the English language...what the surrealists attempted to do for the French language, Céline achieved effortlessly and on a vast scale."From 1937 Céline wrote a series of antisemitic polemical works in which he advocated a military alliance with Nazi Germany. He continued to publicly espouse antisemitic views during the German occupation of France, and after the Allied landing in Normandy in 1944, he fled to Germany and then Denmark where he lived in exile. He was convicted of collaboration by a French court in 1951 but was pardoned by a military tribunal soon after. He returned to France where he resumed his careers as a doctor and author. Céline is widely considered to be one of the greatest French novelists of the 20th century but remains a controversial figure in France due to his antisemitism and activities during the Second World War.

Archibald Joseph Cronin (19 July 1896 – 6 January 1981), known as A. J. Cronin, was a Scottish physician and novelist. His best-known novel is The Citadel (1937), about a Scottish doctor who serves in a Welsh mining village before achieving success in London, where he becomes disillusioned about the venality and incompetence of some doctors. Cronin knew both areas, as a medical inspector of mines and as a doctor in Harley Street. The book exposed unfairness and malpractice in British medicine and helped to inspire the National Health Service. The Stars Look Down, set in the North East of England, is another of his best-selling novels inspired by his work among miners. Both novels have been filmed, as have Hatter's Castle, The Keys of the Kingdom and The Green Years. His 1935 novella Country Doctor inspired a long-running BBC radio and TV series, Dr. Finlay's Casebook (1962–1971), set in the 1920s. There was a follow-up series in 1993–1996.

Theodor Albrecht Edwin Klebs (6 February 1834 – 23 October 1913) was a German-Swiss microbiologist. He is mainly known for his work on infectious diseases.

He was the first to identify a bacterium that causes diphtheria, which was called Klebs–Loeffler bacterium (now Corynebacterium diphtheriae). He was the father of physician Arnold Klebs.
