Actually, Marcellin Gilbert Desboutin came from a well-off, cultured background. He was born in Cérilly in 1823. His mother was an aristocrat, and Marcellin was a wealthy young man whose dabblings in literature and art were enthusiastic hobbies rather than career choices. He bought himself a grand villa outside Florence, where he lived from 1854, dealing in old master paintings, gambling, and generally squandering his fortune. During this time, Desboutin maintained contacts with the Paris art world, and was particularly close to Degas. In Florence he met and encouraged the Italian Impressionist Giuseppe de Nittis, with whom he remained on close terms; there exists a drypoint portrait of Degas about which experts remain divided as to whether it is by Desboutin or de Nittis.
Marcellin Desboutin returned to Paris in 1873, at the age of 50, having ruined himself with unwise investments. Here he returned seriously to art, both painting and printmaking. Desboutin specialized in portrait drypoints, often of fellow artists such as his friends Degas, Renoir, Manet, Morisot, Raffaëlli, Goeneutte and Guérard, but also of authors such as Dumas fils, Zola, and Verlaine. Desboutin's technique was to quickly sketch a portrait on copper with a drypoint needle, to catch his subject in as relaxed and lifelike a pose as possible.
One of Desboutin's portraits of artists, that of Pierre-Cécile Puvis de Chavannes, uses a very interesting mixed technique, invented by Félicien Rops and used infrequently by artists such as Louis Legrand and Desboutin. Based on a painting by Desboutin now in the Musée d'Amiens, this print involved making a héliogravure plate after a painting (as in this case) or an etching that needed to be reduced in size (as in the case of Legrand's La parole divine, my only other example of this process); the artist then worked on top of the heliogravure with a drypoint needle, thus producing a strange hybrid between a reproduction and an original print. The composition in the background is part of Puvis's Bois sacré.
Another artist portrait, that of the etcher Jules Jacquemart, strikes me as possibly originating in a photograph, though Jacquemart was still alive when it was made, so I may be wrong - certainly neither the publisher, the Gazette des Beaux-Arts, nor the cataloguer, Clément-Janin, suggest this to be the case.
It's interesting to compare the vivacity of Desboutin's portraits from life, such as those of Goeneutte and Renoir, with the eight drypoint portraits of singers and dancers for the anonymous work L'Opéra, Eaux-fortes et Quatrains in 1876 (the author was Henry Cohen). Seven of these are drawn after photographs rather than from life, and although they have great charm, they are much stiffer and more conventional than the free depictions of his friends; the exception is the portrait of Léontine Beaugrand. On all eight the printer, Vve Cadart, has misspelled the artist's name as Desboutins.

Despite his late start, Desboutin achieved some fame and success as an artist in the Bohemian circle of Manet and Degas; he exhibited six works at the Second Impressionist Exhibition. The catalog of his works in Clément-Janin's La Curieuse Vie de Marcellin Desboutin lists 246 original prints and 30 "gravures de réproduction" after artists such as Israëls, Fragonard, and Rembrandt; there's also an impressive list of paintings, showing Desboutin to have been hard at work at his art from 1873 to his death.
From 1880 Desboutin lived mostly in Nice, where he died in 1901.
