huinventors1-9, Exercise 3: A careful claim

Model answer (Dennis Gábor):

"Dennis Gábor, born in Budapest in 1900 and educated in Hungary and Germany, devised the principle of holography in 1947 while working in Britain, and won the Nobel Prize in Physics for it in 1971. Here 'Hungarian' means Hungarian-born, and his key contribution was the principle, with the practical holograms made possible later by the laser."

Any inventor from the course is acceptable if the sense of "Hungarian" and the contribution are both stated. Details should be checked.
