Benjamin Rubin

1917 - 2010

He was an American microbiologist, known as the inventor of bifurcated vaccination needle, which played an important role in the eradication of smallpox.He invented this device by taking the eyelet of a sewing machine needle and grinding it down.

Raymond Damadian

1936

He is an American medical practitioner and the first inventor of MRI scaning machine. His reserch into soldium and pottasium in living cells led him to his first experiments with nuclear magnetic resonance which caused him to the first propose the MR body scanner in 1969. Damadian was the first perform a full body scan of a human being to diagnose cancer.
