The foundations of modern medicine were laid down 2000 years ago in Greece. It was the ingenuity of one man Hippocrates- who stressed careful clinical examination, documentation and scientific logic that delivered medicine from quackery and propelled it towards becoming an art and a science. Hippocrates also advised on how a doctor should behave in society and bound all his colleagues- for ages to come- by an oath. This oath continues to be sworn by medical graduates even today.
