@whitequark✧✦Catherine✦✧ Wasn't there also a guy who inserted something into his beating heart to take an X-ray of it, then to get fired for inserting that thing into his live beating heart, and then to get re-hired because that basically proves you can do that, and winning something like a nobel prize?

Yeah.

In 1929, while working in Eberswalde, he performed the first human cardiac catheterization. He ignored his department chief and persuaded the operating-room nurse in charge of the sterile supplies, Gerda Ditzen, to assist him. She agreed, but only on the promise that he would do it on her rather than on himself. However, Forssmann tricked her by restraining her to the operating table and pretending to locally anaesthetise and cut her arm whilst actually doing it on himself.... They walked some distance to the X-ray department on the floor below where under the guidance of a fluoroscope he advanced the catheter the full 60 cm into his right ventricular cavity. This was then recorded on X-ray film showing the catheter lying in his right atrium.[3]

The head clinician at Eberswalde, although initially very annoyed, recognized Werner's discovery when shown the X-rays; ... once Sauerbruch saw his paper, he was dismissed for continuing without his approval.

... some major Nazi things happened here, and he got imprisoned into a PoW camp...

During the time of his imprisonment, his paper was read by André Frédéric Cournand and Dickinson W. Richards. They developed ways of applying his technique to heart disease diagnosis and research. In 1954, he was given the Leibniz Medal of the German Academy of Sciences. In 1956, the Nobel Prize in Physiology or Medicine was awarded to Cournand, Richards, and Forßmann.[1]

So yeah, kinda par for the course.
