1880 deaths

Carl Feer-Herzog (23 October 1820 – 14 January 1880) was a Swiss politician and President of the Swiss National Council (1874).

Josephine Caroline Lang (14 March 1815 – 2 December 1880) was a German composer. Josephine Lang was the daughter of Theobald Lang, a violinist, and Regina Hitzelberger, opera singer. Her mother taught young Josephine how to play piano, and from age five it became apparent that Josephine was possessed with great potential as a composer. As early as age eleven Josephine started giving piano lessons herself. Through her godfather, Joseph Stieler, Josephine was exposed to some of the greatest artists of her time. Both Felix Mendelssohn and Ferdinand Hiller went to great lengths to ensure that Lang learned the proper theory for song-writing, and used their connections to publish Lang's music. Even Robert Schumann published a song of Josephine's in Neue Zeitschrift für Musik in 1838.

Georg Eduard Hallberger, after 1869: von Hallberger (29 March 1822, Stuttgart - 29 August 1880, Tutzing) was a German publisher and businessman.

Wilhelm Ganzhorn (1818–1880) was a German judge and lyricist known for his 1851 song "Im schönsten Wiesengrunde". The melody of "Gi Talo Gi Halom Tasi", which is the regional anthem of the Northern Mariana Islands, is based on it.

Dominique Alexandre Godron (25 March 1807 - 16 August 1880) was a French physician, botanist, geologist and speleologist born in the town of Hayange, in the département Moselle.
Godron studied medicine at the University of Strasbourg, and during his career distinguished himself in natural sciences as well as in the field of medicine. In 1854 he became dean and professor of natural history to the Faculty of Sciences at Nancy. Here he established a natural history museum and reorganized its botanical garden (now the Jardin Dominique Alexandre Godron, renamed in his honor).
Among his numerous writings were a publication on the flora of the Lorraine region of France called "Flore de Lorraine" (1843), and the three-volume "Flore de France", a work on flora native to France and Corsica that was co-written with botanist Jean Charles Marie Grenier (1808-1875). In addition to his botanical works, he published a number of studies in the field of ethnology.Before Mendel, he discovered the main features of hybridation. In "de l'Espece et des races dans les êtres organises" he also demonstrated that hybridization in the vegetal world was, against the dominant thinking at the time, similar to hybridization in the animal world. He finally demonstrated the unity of mankind in his book dedicated to our species.
In 1846, he was honoured by botanists Jean Baptiste Mougeot and Joseph Henri Léveillé who named Godronia, which is a genus of fungi in the family Helotiaceae. Then in 1927, William Webster Diehl and Edith Katherine Cash published Godroniopsis, which is also a genus of fungi in the family Helotiaceae.

Alexandre Edouard Baudrimont (7 May 1806 – 24 January 1880) was a 19th-century French professor of chemistry who published various books connected to the sciences, languages and the Basque Country (in particular Erromintxela):

Dictionnaire de l'industrie manufacturière, commerciale et agricole (1837, Paris)
Recherches anatomiques et physiologiques sur le développement du fœtus: et en particulier sur l'évolution embryonnaire des oiseaux et des batraciens (with Martin Saint-Ange, G.J.) (1846)
Histoire des Basques ou Escualdunais primitifs, restaurée d'après la langue, les caractères ethnologiques et les mœurs des Basques actuels (1854, Paris)
Vocabulaire de la langue des Bohémiens habitant les Pays Basque Français (1862, Bordeaux)In the field of science he is best known for first preparation of Na3P in the mid-19th century by reacting molten sodium with phosphorus pentachloride.

Édouard Séguin (January 20, 1812 – October 28, 1880) was a French physician and educationist born in Clamecy, Nièvre. He is remembered for his work with children having cognitive impairments in France and the United States.

Alphonse Pénaud (31 May 1850 – 22 October 1880), was a 19th-century French pioneer of aviation design and engineering. He was the originator of the use of twisted rubber to power model aircraft, and his 1871 model airplane, which he called the Planophore, was the first aerodynamically stable flying model. He went on to design a full-sized aircraft with many advanced features, but was unable to get any support for the project, and eventually committed suicide in 1880, aged 30.

Mario Tiberini (8 September 1826 – 16 October 1880) was an Italian tenor who sang leading roles in the opera houses of Europe and the Americas in a career spanning 25 years. Known for his advanced singing technique and dramatic ability, he sang the role of Alvaro in the premiere of the revised (and now standard) version of Verdi's La forza del destino and created several roles in operas by lesser-known composers, including the title role in Faccio's Amleto.

Jules Antoine Lissajous (French pronunciation: [ʒyl ɑ̃twan lisaʒu]; 4 March 1822 in Versailles – 24 June 1880 in Plombières-les-Dijon) was a French physicist, after whom Lissajous figures are named. Among other innovations, Lissajous invented the Lissajous apparatus, a device that creates the figures that bear his name. In it, a beam of light is bounced off a mirror attached to a vibrating tuning fork, and then reflected off a second mirror attached to a perpendicularly oriented vibrating tuning fork (usually of a different pitch, creating a specific harmonic interval), onto a wall, resulting in a Lissajous figure. This led to the invention of other apparatus such as the harmonograph.
