I agree. A classic example is the story of the semiconductor and radio. The popular history said that the point-contact transistor was invented in 1947 at Bell Labs and started the age of semiconductors. But do you know that Russian physicist Oleg Losev (also a pioneer of LED) discovered negative resistance in zinc-oxide diodes in 1923, and built solid-state amplifiers, oscillators, regenerative and superheterodyne r…
Negative resistance devices are very tricky to use since you need a non reciprocal element. Bell created a design that was commercially useful and widely applicable and later iterations (contact, planar BJT) cam from it.
Sure...
I'm not an engineer, but I read that tunnel diodes were hailed as the greatest innovation in semiconductor of the 1960s, and it was often the only available option in high-frequency applications, but they were almost completely abandoned when integrated circuits became feasible. Leaving the embarrassing situation that the tunnel diodes in lot of vintage Tektronix oscilloscopes are unobtainium.

This is kind of the point made by the original comment. Arguing about the "first" sometimes is a waste of time, it's better to list all the codiscoverers and discuss their respective contributions.
