Divisumma 18 Calculator

This is a Calculator. It was designed by Mario Bellini. It is dated 1973 and we acquired it in 1986. Its medium is abs plastic, melamine, rubber, metal. It is a part of the Product Design and Decorative Arts department.

With the intent to design a piece of “totally humanized” office technology, Bellini attracted a new breed of consumer with the Divisumma 18 calculator’s colorful, tactile form. The stylish design made use of revolutionary synthetics like ABS plastic, melamine resin, and an inviting rubberized skin covering the keyboard buttons. Produced in a bright golden hue, it sat smartly on desks as a reminder of the sense of play that design could bring to even the most formal environments.

This object was donated by Barry Friedman and Patricia Pastor. It is credited Gift of Barry Friedman and Patricia Pastor.
