>Werner Forssmann performed the first heart catheterization on himself. He got the Nobel prize.
In case anyone else was confused how it would be possible to perform heart surgery on yourself, he did it through a vein in his arm, which is still incredibly impressive:
>In 1929, he put himself under local anesthesia and inserted a catheter into a vein of his arm. Not knowing if the catheter might pierce a vein, he put his life at risk. Forssmann was nevertheless successful; he safely passed the catheter into his heart.
He also had to trick the operating-room nurse into thinking he was operating on her.
