This is Part Six of a six-part series of news columns that detail the human side of the heart surgeries that took place in the 1950's. How one doctor gave life to many and how one of those people made that life worth living. How that one person - as mother-to-be and then as a mother - was used as an example to nurses of the future that had arrived in Philadelphia. This last article in the series will explain how a life, while not perfect, was made worth living. How knowing that life, no matter how short in duration, could be used to confront silence in the face of evil.
