I want to know the answer to the following question:
Where were Matare and Welker working when inventing the point-contact transistor?
All the background I'm provided with is that "In 1948, the point-contact transistor was independently invented by German physicists Herbert Mataré and Heinrich Welker while working at the Compagnie des Freins et Signaux, a Westinghouse subsidiary located in Paris.". Is that enough to answer the question?
