At the physical heart of the Selectric typewriter’s innovation was a golf-ball-shaped type head that replaced the conventional typewriter’s basket of type bars. The design eliminated the bane of rapid typing: jammed type bars. And with no bars to jam, typists’ speed and productivity soared.

The golf ball typing element was designed by an engineering team led by Horace “Bud” Beattie. The team members, according to a 1961 advertisement for the Selectric, “began their search by forgetting the past fifty years of typewriter design.” The first type head design had been shaped more like a mushroom, but under Beattie’s direction, IBM engineer John Hickerson revised the type head toward its ultimate spherical configuration.

One other innovation in the design—a changeable typeface—was borrowed from a turn-of-the-century model, the Blickensderfer typewriter. Although it is not documented, it is believed that the Selectric name was inspired by adding this changeable typeface selection to an electric typewriter. By making the golf ball interchangeable, the Selectric enabled different fonts, including italics, scientific notation and other languages, to be swapped in.

These IBM golf balls were acquired as part of the Shekou Project, an international partnership between the V&A and China Merchant Shekou Holdings (CMSK) to open a new cultural platform called Design Society in Shekou. It was included in the inaugural exhibition, ‘Values of Design’, in the V&A Gallery at Design Society in a section exploring flexibility as a design value.
