Against the Grain: Defiant Giants Who Changed the World (October 14, 2025, Collins)

Terry O'Reilly, Host, CBC's Under the Influence

Brett Hendrie, Director, Strategic Events, Rotman School of Management

In Terry’s bestselling book, My Best Mistake, he uncovers the surprising power of screwing up. Now, he turns his incredible eye to the mavericks who go “against the grain” in their work to see what makes them tick and to explore what lessons we can learn from them. People who chose to ignore conventional wisdom, found or invented a better way, questioned the status quo at great sacrifice and pushed for change against all odds. Some were drummed out of their careers for it but in the end were proven right (Dr. Ignaz Semmelweis). Some were celebrated but had to fight every inch of the way (Norman Lear). Some re-invented their industry but preferred to stay an outsider (Tom Laughlin—aka Billy Jack). Some confounded their competitors with ingenious strategies (NHL coach Roger Neilson). One even saved millions of people around the world, but was humiliated, demoted, and dismissed for her entire career (Dr. Katalin Karikó—co-creator of the COVID vaccine). All persistent visionaries, each covered in battle scars.
