  Those sources appear to exclude Lilienfeld. He didn't create a good or tool. He didn't create a material. He didn't create a manufacturing process or a control procedure or a method of measurement. Lilienfeld was a brilliant man but he didn't invent transistors any more than Albert Einstein invented gravitational wave detectors.

    The patent doesn't mention the term "transistor"; but obviously the patent office came to the conclusion that it is a patentable invention, and the cited by list confirms that it is considered a relevant invention by Bell Labs and other notable institutions. Prior art by Lilienfeld did even stop some applications of Bell Labs from going forward. The transistor invented in 1947 was a point-contact transistor, which is not the concept applied in micro processors as the article confirms.
