Mario Bellini. Divisumma 18 Electronic Printing Calculator. 1972 | MoMA

It was hard to resist touching the Divisumma 18 calculator when it first appeared on the market. Produced by Olivetti, for whom Bellini began working as a chief industrial design consultant in 1963, it proved to be enormously popular. The Divisumma 18 was small and portable, in contrast to earlier computing machinery, much of which looked like heavy cabinetry.
