Legend has it that Douglas Engelbart invented the mouse in 1968.

But did you know that German television manufacturer Telefunken released a "rolling-ball" device just a few months earlier?

From a technical perspective it actually closely resembles the kind of mouse that we ended up using until the late 90s.

The German patent office declined a patent due to a "lack of inventive step".

@fribbledom Do you know the story of Antonio Meucci's telephone?
The true story is not mentioned here en.wikipedia.org/wiki/Antonio_

@Eidon

In that case I probably do not...

@fribbledom Well the official story is difficult to emerge; for too long Bell has been considered as "the inventor of the telephone". But that's not true. Even wikipedia only tells the official truth, which is not true.
