Roger Fisher (academic)
Roger D. Fisher, who lived from May 28, 1922, to August 25, 2012, was a distinguished law professor at Harvard Law School. He gained recognition for his expertise in negotiation and conflict management. One of his most significant contributions was co-writing the book "Getting to Yes" alongside William Ury. This book introduced the concept of "interest-based" negotiation, which focuses on finding common interests and solutions rather than engaging in adversarial battles.
