Book excerpt: ""Scientists Greater than Einstein"" tells the stories of ten scientists whose discoveries have had an amazing impact on humanity. Combined, these ten scientists have saved more than 1.6 billion lives--and yet, most remain unknown and unheralded. For instance: Do you know about the eye doctor who in the 1970s figured out how to save millions of children with a nickel's worth of medicine? How about the man from the dusty fields of Mexico who has saved hundreds of millions of people from dying of starvation and malnutrition? Everyone knows about Jonas Salk and his polio vaccine. Do you know whose discovery made Salk's vaccine possible and who created the measles vaccine that has saved many more lives than the polio vaccine? Much of the world's population is alive today due to these ten scientists and no one knows their names. Scientists Greater than Einstein will correct this oversight.
