Fitting a full-sized keyboard alongside a 10.4-inch LCD colour display into the next ThinkPad 701C portable laptop was a challenge and to overcome this hurdle, Dr John Karidis, an IBM distinguished engineer went on to develop the “Butterfly” keyboard.
The idea of butterfly keyboard struck when Karidis saw his three-year-old daughter who was building shapes out of her toy blocks.
Karidis thought of cutting the board across the number 4, T, H and M keys. That way the board was broken into two distinctive movable parts and that was how the “Butterfly” keyboard came about.

Karidis fit the full-sized keyboard into a 9.7-inch laptop chassis by dividing the keyboard into two interlocking pieces that folded in and out as you opened and closed the laptop’s lid. When the lid is closed, both pieces lie flat in the case.
The Butterfly keyboard went on to become a game-changing concept to tackle the problem of stuffing a full-sized keyboard into a portable laptop.
ThinkPad 701C holds a spot in MoMA’s permanent collection in New York City and the laptop is in hot demand among the collector community.
