Roger Fisher (1922–2012) was a renowned professor at Harvard Law School and the founder of the Harvard Negotiation Project. He is considered a preeminent authority on conflict resolution due to his decades of academic research and practical experience advising on high-stakes international disputes, including the Camp David Accords and the Iranian hostage crisis. His seminal book, Getting to Yes, revolutionized the field by introducing interest-based, principled negotiation to millions worldwide.
