There are many that could be mentioned, but I would choose the transistor. Both for the idea itself, and for the miriad of new inventions that it spun, ranging from radio to power electronics, from computers and the internet to automation and control.

Too many achievements had taken a place in the last 125 years, but using silicon as a semiconductor material is the greatest technology achievement. This fired up the electronics revolution, such as transistors, solar cells, integrated circuits, microprocessors, semiconductor detectors and other semiconductor devices.
