Abstract : This brief note pushes further back the invention of key-driven calculating machines. Until recently, it was thought that the first such machine was Du Bois D. Parmelee's in 1850. Then, notice was made of Jean-Baptiste Schwilgué's machine (1844), then of Luigi Torchi's (1834), and now of James White's (1822).
