Chemistry:Edward Loysel
Initially professor of mechanics and natural sciences[1] in Marseille, France, he began to move into business in following years.[2] In the early 1840s, he first patented an advertising panel and a chess game.[1]
Later on, Loysel built over existing work undertaken by Jöns Jacob Berzelius in Sweden, the Count of Real and Pierre-François-Guillaume Boullay in France, and other techniques developed in Germany,[3][4] to patent in 1845 his "Hydrostatic percolator" described as "devices, intended to obtain, by infusion, liquid extracts and various substances".[5]
Mainly used for coffee, the machine was exhibited at the 1855 Paris Exposition.[6] As Loysel had moved to the UK in 1844 (and obtained British nationality in 1848), his machine was presented as part of the "English catalogue" of the world fair.[1][2] In London, he was member of the Institution of Civil Engineers.
The success of Loysel's machine was also ensured by its capacity to produce hundreds of cups of coffee per hour.[6][7]
