After the success of the Olivetti Valentine, Ettore Sottsass and Hans von Klier teamed up again to design the Summa 19 mechanical calculator. Again, they would win the Golden Compass award in 1970 but the calculator itself was not that successful due to smaller electronic calculators produced by competitors.
