But surely the transistor was actually invented around 1923, by Dr. J. Edgar Lilienfeld, and patented in 1925.
He also patented the "electrolytic condenser" based on oxide films in 1931.
However, his devices were MOSfets and thin-film fets and never gained any traction, perhaps as they had poor characteristics compared to valves, due in part to the poor purity of the silicon then available. Yes, the first transistors were silicon, not germanium.
So should we wait another 2 years and celebrate 100 years of the transistor?
