Columbus ship replicas, 1905
Columbus ship replicas, circa 1905, in Jackson Park, Chicago, USA. These ships (from left: the Santa Maria, Nina, and Pinta) were used by Italian explorer Christopher Columbus on his 1492 voyage to discover the Americas. Made for the World's Columbian Exposition of 1893, the original replicas had sunk or been destroyed by the 1920s. In the background (centre) is La Rabida Children's Hospital (originally a replica of the Spanish La Rabida Monastery). It was rebuilt after being destroyed by fire in 1922. At lower left are men in a hand-cycle (left) and a tricycle (right). Photograph from a 1906 Detroit Publishing Company catalogue.

Joseph Plateau, Belgian physicist
Joseph Antoine Ferdinand Plateau (1801-1883), Belgian (Wallonian) physicist and pioneer in optical devices. Plateau studied at the University of Liege. He then taught mathematics and published on the mixing of colours leading to his doctorate. In the 1830s, he invented optical devices: the anorthoscope and phenakistiscope (an early stroboscopic device). He became professor of physics at the University of Ghent in 1835, but by 1843 had become blind. He continued to work in physics, publishing collections of his research on a range of topics including liquid films, surface tension, irradiation and hydrostatics. This wood engraving dates from circa 1888.
