Vocation : Medical : Physician

Adolf Weil (7 February 1848, Heidelberg – 23 July 1916, Wiesbaden) was a German physician after whom Weil's disease is named.
Weil studied medicine at the University of Heidelberg, and afterwards furthered his education in Berlin and Vienna. From 1872 to 1876 he was an assistant to Friedrich Theodor von Frerichs (1819–1885) in Berlin. In 1886, he was appointed professor of special pathology and therapy at the University of Dorpat, but resigned shortly afterwards, after contracting tuberculosis of the larynx and permanently losing his voice. Later he lived and worked in Ospitaletto, San Remo and Badenweiler, relocating to Wiesbaden in 1893, where he died in 1916.
In 1913, in collaboration with Emil Abderhalden (1877–1950) he isolated an alpha-amino acid known as norleucine. Among his written works was a treatise on the auscultation of arteries and veins, Die Auscultation der Arterien und Venen (1875), and a monograph titled Handbuch und Atlas der topographischen Percussion (Handbook and atlas of topographical percussion) (1877).Shortly after receiving news that Weil's disease was caused by a spirochete, he died of acute hemoptysis.

Gérard Daniel Westendorp (8 March 1813, The Hague – 31 January 1869, Dendermonde) was a Dutch born, Belgian military physician and botanist.
He studied medicine at the Ecole de Médecine de Bruxelles, later working as a student-physician in Antwerp. Around 1834, he became a naturalized citizen of Belgium, subsequently serving as an assistant army and navy physician, later spending his career as a "regular doctor" in the Belgian army.As a botanist, he specialized in cryptogamic flora, being the co-publisher (with A.C.F. Wallays) of a cryptogamic exsiccatae series of Belgium. He also made significant contributions towards the "Prodromus Florae Batavae" project (1850-1866). In the field of zoology, he published a treatise on Bryozoa and sponges of Belgium.Westendorp's botanical specimens are preserved in the Jardin Botanique National de Belgique.

Carolina Beatriz Ângelo (16 April 1878 – 3 October 1911) was a Portuguese physician and the first woman to vote in Portugal.

Kurt Warnekros (November 15, 1882–September 30, 1949) was a German gynaecologist and pioneer in sex reassignment surgery.

Carlos Sylvestre Begnis (30 August 1903 – 22 September 1980) was a medical doctor and politician, born in Alto Grande, a village near Bell Ville, Córdoba province in Argentina. He was a rural physician and worked as a surgeon in hospitals of the city of Rosario, province of Santa Fe.
He entered politics through the Radical Civic Union. In 1958 he was elected governor of Santa Fe, following a period of de facto military rule (after the Revolución Libertadora, which had ousted president Juan Perón three years before). He became a part of the Intransigent Radical Civic Union (UCRI), and then formed part of the leadership of the Movement for Integration and Development (MID). His term was ended by a federal intervention.
In the 1970s, Sylvestre Begnis moved to the Justicialist Party (Peronism), and was elected governor again in 1973 (Argentina had just emerged from seven years of military dictatorship). The Hernandarias Subfluvial Tunnel, which joins Santa Fe and Entre Ríos under the Paraná River, was built during his administration, and then officially renamed after him and Entre Ríos governor Raúl Uranga. The Brigadier Estanislao López Highway, linking Rosario and Santa Fe (the two largest cities in the province), was also built at this time. Sylvestre Begnis followed the policies of desarrollismo, sponsored by the national government of president Arturo Frondizi, devoting a large share of the provincial budget to public works (schools, roads, electric power lines, hydraulic works).
Sylvestre Begnis again could not complete his term, being removed from office in 1976 as a result of the military coup that started the dictatorship of the National Reorganization Process. He died of acute leukemia in 1980, at the age of 77.
His son Juan Héctor, also a politician, was a candidate for vice governor and served the Justicialist government of Jorge Obeid as Minister of Health, and is a national deputy for the Front for Victory. He chairs the Health Committee of the Argentine Chamber of Deputies. In 2007 he campaigned to be mayor of Rosario.

Julius Stumpf (1836 - 1932) was a German physician and scientist who used white clay from Germany to treat a deadly form of Asian cholera, diphtheria, gangrene, ulcers of the tibia and the skin disease eczema. He worked at the University of Würzburg.

Alexander Spengler (20 March 1827 – 11 January 1901) was a Swiss physician of German origin and the first physician specializing in tuberculosis in Davos.
Spengler was born as the eldest son of Johann Philipp Spengler, a teacher at a school in Mannheim. Starting in the autumn of 1846, he studied five terms at the University of Heidelberg.
Spengler had taken part in the Baden Revolution of 1848/1849 as a law student. After the defeat of the revolution, he was expatriated for desertion from the Grand Duchy of Baden in 1850. He fled to Zurich, where he studied medicine. In 1853, the stateless refugee got a job in Davos, which was remote at the time. His observation that pulmonary tuberculosis did not occur in Davos and that sick people returning home improved, marked the beginning of the development of the modern high-altitude health resort of Davos. Spengler was able to acquire Swiss citizenship in 1855.
Spengler was the father of Carl Spengler and Lucius Spengler, both pulmonologists in Davos.
