Historical moment essay Public Understanding of Science 00(0) significant role in the introduction of science and technology to the Netherlands, while being, at the same time, able to navigate successfully between different audiences and institutional settings. 1. From conjuror to lantern lecturer Levie Kinsbergen was born in Zutphen, a small city in the east of the Netherlands, on 17 August 1823. His birth certificate ('Levie Kinsbergen', 1823) names his mother Mietje van Huuks, housewife, and his father Meijer Kinsbergen, showman in Amsterdam. Meijer already used the stage name Maju Kinsbergen or Kinsbergen Maju, before it was adopted by his son (Overijsselsche Courant, 1823). The Kinsbergen family was a Dutch Jewish family with many connections to the entertainment industry, namely itinerant shows in Dutch fairgrounds. 2 During the 1850s, L. K. Maju styled himself as Professor of Sleight-of-Hand and toured the country's theater venues, coffee houses, and fairgrounds with Soirées Amusantes, which included conjuring acts and experimental physics (Bredasche Courant, 1857; Provinciaal Dagblad van Noord-Brabant en's Hertogenbossche Stads-Courant, 1852). Between 1863 and 1864, Maju worked in London, where he performed conjuring feats "without any apparatus" at the Royal Colosseum and the Royal Polytechnic Institution under the stage names L. Kinsbergen Maju, Professor of Magic to the King of Holland or Herr Maju, the Great Prestidigitateur (Lloyd's Weekly Newspaper, 1864; The Globe, 1863). Maju's association with the Polytechnic turned out to be a fruitful and long-lasting endeavor that widened the scope of his performances. In the following years, Maju exported the Polytechnic's sensational ghost lecture, Pepper's Ghost, which would become known in the Netherlands as De Geest van Maju (The Ghost of Maju in a literal translation), and the cabinet-based illusion The Sphinx. The Ghost was performed mainly as an itinerant act on Dutch fairgrounds between 1864 and 1865 (Algemeen Handelsblad, 1864; Rotterdamsche courant, 1865). While it was a very different setting from the rational entertainment environment of the Polytechnic, this choice enabled Maju to include the Ghost in a profitable circuit, reaching audiences across the Netherlands, while making use of his family network. When Maju imported The Sphinx from the Polytechnic in 1866, he skipped the fairground circuit and performed the illusion in permanent indoor theaters throughout the country, following the first very successful performances at the Paleis voor Volksvlijt, which was referred to as the Dutch Crystal Palace (Algemeen Handelsblad, 1866). Later that year, Maju started to add other acts (such as microscopic and agioscopic, or opaque, projection) to the short piece that was The Sphinx and to offer evening programs which included three to four sections, lasted about 2 hours and which he advertised as scientific performances (Utrechtsch Provinciaal en Stedelijk Dagblad, 1866). Maju quickly devised a new repertoire based on magic lantern lectures and technol...
