Short answers, pulled from the story.
Gustave Doré created over 10,000 illustrations. The most significant of these were reproduced via an electrotype process using cylinder presses, enabling large print runs to be distributed simultaneously across many countries.
Doré is best known for his illustrations of the Vulgate Bible (1866), Dante's Divine Comedy, Cervantes's Don Quixote (1863), Milton's Paradise Lost (1866), and Coleridge's Rime of the Ancient Mariner (1875). His 1863 Don Quixote ran to 370 illustrations and shaped how later artists, stage directors, and filmmakers imagined the physical appearance of the knight and Sancho Panza.
Gustave Doré was born in Strasbourg on the 6th of January 1832. He died in Paris on the 23rd of January 1883 following a short illness.
The Doré Gallery was a permanent exhibition space founded on Bond Street, London, following the success of a major exhibition of Doré's work held there in 1867. The gallery also served as the publisher for his 1875 folio edition of The Rime of the Ancient Mariner.
London: A Pilgrimage, published in 1872 with 180 wood engravings, was criticized by some British critics for focusing on the poverty of the city rather than its more flattering aspects. The Art Journal accused Doré of inventing rather than copying, and The Westminster Review claimed he had recorded only the vulgarest external features. Vincent van Gogh, however, was impressed enough to paint a version of the book's Prisoners' Round image in 1890.
Doré designed all compositions himself but employed up to 40 specialist block-cutters to translate his drawings onto wooden printing blocks; those cutters typically also signed the finished image. The key prints were then copied using an electrotype cylinder-press process that allowed very large editions to be published simultaneously in multiple countries.
