Oscar Pletsch (26 March 1830 – 12 January 1888) was a German illustrator.

Hermann Seeger (15 October 1857 – 23 February 1945) was a German genre and landscape painter. Seeger was also known as a talented engraver.

Louis Aston Knight (1873 — 1948) was a French-born American artist noted for his paintings of landscapes. One of his paintings, The Afterglow, was purchased by U.S. President Warren G. Harding in 1922 to hang in the White House.

Émile Nouguier (17 February 1840 – 23 November 1897) was a French civil engineer and architect. He is famous for co-designing the Eiffel Tower, built 1887–1889 for the 1889 Universal Exposition in Paris, France, the Garabit viaduct, the highest in the world at the time, near Ruynes-en-Margeride, Cantal, France, and the Faidherbe Bridge over the Sénégal River in Senegal.
In 1861 he attended and graduated the École Polytechnique in Paris, in 1862 he joined the École nationale supérieure des mines de Paris from which he graduated in 1865 with the title of mining construction engineer.

Sir William Russell Flint (4 April 1880 – 30 December 1969) was a Scottish artist and illustrator who was known especially for his watercolours of women. He also worked in oils, tempera, and printmaking.

Joseph Thomson (14 February 1858 – 2 August 1895) was a British geologist and explorer who played an important part in the Scramble for Africa. Thomson's gazelle and Thomson's Falls, Nyahururu, are named after him. Excelling as an explorer rather than an exact scientist, he avoided confrontations among his porters or with indigenous peoples, neither killing any native nor losing any of his men to violence. His motto is often quoted to be "He who goes gently, goes safely; he who goes safely, goes far."

Paul Marie Oudin (1851–1923) was a French physician and medical researcher. He was born, and later died, in Épinal. He conducted research in the Victorian era medical field of high frequency electrotherapy, the application of radio frequency electric currents to the body, and collaborated with the founder of the field, pioneering physiologist and biophysicist Dr. Jacques Arsene d'Arsonval. In 1893 he modified d'Arsonval's electrotherapy equipment by the addition of a wire coil resonator to produce higher potentials, inventing the Oudin coil. This device, very similar to a Tesla coil, could produce very high voltages from several hundred thousand to a million volts. In use, the brush discharges from a pointed electrode attached to the high voltage terminal of the coil would be played over various parts of the body to treat a variety of medical conditions. The Oudin coil was used in electrotherapy and diathermy through the 1920s.

Claude Félix Abel Niépce de Saint-Victor (26 July 1805, Saint-Cyr, Saône-et-Loire – 7 April 1870, Paris) was a French photographic inventor. Claude was an army lieutenant and the cousin of Nicéphore Niépce. He first experimented in 1847 with negatives made with albumen on glass, a method subsequently used by Frederick Langenheim for his and his brother’s lantern slides. At his laboratory near Paris, Saint-Victor worked on the fixation of natural photographic colour as well as the perfection of his cousin's heliographing process for photomechanical printing. His method of photomechanical printing, called heliogravure, was published in 1856 in Traité pratique de gravure héliographique. In the 1850s, he also published frequently in La Lumière.

Raoul Grimoin-Sanson (1860–1941) was an inventor in the field of early cinema. He was born in Elbeuf, as Raoul Grimoin; he added the surname Sanson later. He had an early interest in stage magic as well as photography.
In the 1890s, Grimoin-Sanson began experiments in moving pictures, and desired to project films, like those from Thomas Edison's kinetoscope, on screen. In 1896, he invented a crude camera/projector combination called the Phototachygraphe. In 1897, he patented the Cinéorama, a panoramic film projection system involving ten synchronized projectors. The Cinéorama was demonstrated at the 1900 Exposition Universelle in Paris, but problems with heat from the projectors caused it to be shut down. Despite the failure of his Cinéorama company and of later film work, in the 1920s Grimoin-Sanson would attempt to claim to be one of the major pioneers of film, alongside Marey and the Lumières.

Antoine Hercule Romuald Florence (February 29, 1804 – March 27, 1879) was a Monegasque-Brazilian painter and inventor, known as the isolate inventor of photography in Brazil, three years before Daguerre (but six years after Nicéphore Niépce), using the matrix negative/positive, still in use. According to Kossoy, who examined Florence's notes, he referred to his process, in French, as photographie in 1834, at least four years before John Herschel coined the English word photography.
