In proving the existence of stem cells, Ernest Armstrong McCulloch and James Edgar Till formed the most important partnership in Canadian medical research since Frederick Banting and Charles Best, the discoverers of insulin. Together, Till and McCulloch instructed, influenced, and inspired successive generations of researchers who have used their findings to make huge advances against disease. Thousands of people who would have died from leukemia and immunological disorders now owe their lives to therapies developed from their discoveries.


Despite their accomplishments, Till and McCulloch remain largely unknown, and until now, their story has remained untold. Dreams and Due Diligence vividly chronicles the work of two researchers who made medical history – two men who possessed exactly the right complementary talents to achieve greatness and win nearly every award available in medical research. Bringing their legacy to life for the first time, Joe Sornberger provides a dramatic account of the development of stem cell research, one of today's most ground-breaking medical scientific fields.
