1901 deaths

Giuseppe Fortunino Francesco Verdi (Italian: [dʒuˈzɛppe ˈverdi]; 9 or 10 October 1813 – 27 January 1901) was an Italian composer best known for his operas. He was born near Busseto to a provincial family of moderate means, receiving a musical education with the help of a local patron, Antonio Barezzi. Verdi came to dominate the Italian opera scene after the era of Gioachino Rossini, Vincenzo Bellini, and Gaetano Donizetti, whose works significantly influenced him.
In his early operas, Verdi demonstrated sympathy with the Risorgimento movement which sought the unification of Italy. He also participated briefly as an elected politician. The chorus "Va, pensiero" from his early opera Nabucco (1842), and similar choruses in later operas, were much in the spirit of the unification movement, and the composer himself became esteemed as a representative of these ideals. An intensely private person, Verdi did not seek to ingratiate himself with popular movements. As he became professionally successful, he was able to reduce his operatic workload and sought to establish himself as a landowner in his native region. He surprised the musical world by returning, after his success with the opera Aida (1871), with three late masterpieces: his Requiem (1874), and the operas Otello (1887) and Falstaff (1893).
His operas remain extremely popular, especially the three peaks of his 'middle period': Rigoletto, Il trovatore and La traviata. The bicentenary of his birth in 2013 was widely celebrated in broadcasts and performances.

Henri Hyacinthe Helle (4 September 1873 in Thiescourt – 21 June 1901 in Thiescourt) competed for France at the 1900 Summer Olympics, in archery. Helle competed in two events, taking second place[1] in the 50 metre Au Chapelet event and fourth place in the 50 metre Au Cordon Doré competition. His score of 27 points in the Au Cordon Doré was one point behind the third-place archer, Émile Fisseux. No scores are known for the Au Chapelet competition.

Joseph Adolphe Théophile Olivier (2 December 1874 in Paris – 21 May 1901 in Neuilly-sur-Seine) was a French rugby union player who competed in the 1900 Summer Olympics. He was a member of the French rugby union team, which won the gold medal.

Mathilde Weber (1829–1901), was a German feminist and social worker, regarded as one of the founders of the German women's movement. She focused on getting academic studies available for women.

Count Wilhelm Otto Albrecht von Bismarck-Schönhausen (1 August 1852 – 30 May 1901) was a German counselor, civil servant and politician, who served as a member of the Reichstag from 1880 to 1881 and president of the Regency of Hanover from 1889 to 1890. The youngest son of Otto von Bismarck, he and his brother Herbert von Bismarck both resigned their posts after the elder Bismarck was dismissed as Chancellor of Germany in 1890. Wilhelm subsequently accepted an appointment as Governor of East Prussia in 1894. Mount Wilhelm (German: Wilhelmsberg, or in Kuman: Enduwa Kombuglu, or Kombugl'o Dimbin) the highest mountain in Papua New Guinea at 4,509 metres (14,793 ft), part of the Bismarck Range, was named after him by Hugo Zöller.

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.

Euphrosine Beernaert (11 April 1831 – 7 July 1901) was a Belgian landscape painter.

Félix Joseph Henri de Lacaze-Duthiers (15 May 1821 – 21 July 1901) was a French biologist, anatomist and zoologist born in Montpezat in the department of Lot-et-Garonne. He was a leading authority in the field of malacology.He studied medicine in Paris, and worked at Necker Hospital under Armand Trousseau (1801–1867). Later on, with Jules Haime (1824–1856), he travelled to the Balearic Islands to study marine life. In 1854 he returned to Paris as an assistant to Henri Milne-Edwards (1800–1885), and soon afterwards became a professor of zoology in Lille.
In 1865 he succeeded Achille Valenciennes (1794–1865) as chair of histoire naturelle des mollusques, des vers et des zoophytes at the National Museum of Natural History, France, and in 1868 became a professor at the University of Paris. In 1871 he was elected to French Academy of Sciences in the department of anatomy and zoology.

Lacaze-Duthiers is remembered for his study of the anatomy and developmental history of mussels, coral, snails, brachiopods and other invertebrate marine animals. In 1858 he discovered three mollusks in the Mediterranean that produced purple-blue dyes. One of the species, named murex trunculus, was the source of the distinctive purple-blue dye used by the ancient Phoenicians and Canaanites. He realised the dying process could be used to create a photographic image in purple-blue dye which he named the Mucographé process. Examples are preserved in the Sorbonne and the Royal Society in London.
He conducted pioneer exploration of marine life of coastal Algeria, that included scientific studies of coral. A result of this research was the publication of "Histoire naturelle du corail" (1864).He was the founder of two laboratories devoted to marine biology; the biological station at Roscoff in 1876, and the Arago laboratory at Banyuls-sur-Mer in 1882. A number of species bear his name, a few of them being: Strophomenia lacazei, Convoluta lacazi and Dileptus lacazei. In 1872 he founded the journal "Archives de zoologie expérimentale et générale" (Archives of Experimental and General Zoology).

Max Joseph Pettenkofer, ennobled in 1883 as Max Joseph von Pettenkofer (3 December 1818 – 10 February 1901) was a Bavarian chemist and hygienist. He is known for his work in practical hygiene, as an apostle of good water, fresh air and proper sewage disposal. He was further known as an anti-contagionist, a school of thought, named later on, that did not believe in the then novel concept that bacteria were the main cause of disease. In particular he argued in favor of a variety of conditions collectively contributing to the incidence of disease including: personal state of health, the fermentation of environmental ground water, and also the germ in question. He was most well known for his establishment of hygiene as an experimental science and also was a strong proponent for the founding of hygiene institutes in Germany. His work served as an example which other institutes around the world emulated.

Ernest Jean Philippe Fauque de Jonquières (born Carpentras, France 3 July 1820; died Mousans-Sartoux, France 12 August 1901) was a French mathematician and naval officer who made several contributions in geometry.
Jonquières attended the naval school at Brest, and later joined the French Navy. in 1841 he became a lieutenant, and from 1849 to 1850 he served on the staff of the Admiral in Paris. During this time, Jonquières became a close associate of Michel Chasles, whose works he had studied. During his subsequent time at sea, he continued his mathematical studies, and won a part of the Grand Prix of the French Academy of Sciences in 1862.
In 1865, Jonquières became a captain and was sent to Saigon to organize a French agricultural and industrial exhibition. He played an important role in the development of current Vietnam as a French colony. Later, he was head of the local naval depot and its maps and plans. In 1874, Jonquières was made Vice-Admiral. He retired in 1885.
