Remembering Dr. Donald Hawkins

Professor Donald E. Hawkins was far more than Solimar International’s chairman. He was a teacher, mentor, advisor, and unwavering champion of the company from its earliest days. As a professor and mentor to Solimar’s founders, Don helped shape not only their thinking, but also the values that continue to guide our work: that tourism should serve communities, protect cultural and natural heritage, and create lasting, inclusive value.
Throughout Solimar’s journey, Don remained our “Chief Cheerleader.” He believed deeply in the company’s mission and stood by us through every success, setback, and reinvention with wisdom, encouragement, and optimism. His guidance grounded our work in purpose and principle, and his faith in our team never wavered.
Don’s legacy extended far beyond Solimar. At George Washington University, he was a foundational figure who helped establish tourism as a serious field of academic study and practice. Over more than five decades, he played a central role in building GW’s Master of Tourism Administration program and advancing the International Institute of Tourism Studies, while mentoring generations of students who became leaders across the global tourism field.
A globally respected advisor and practitioner, Don worked with governments, development banks, international organizations, and destination leaders around the world. Long before sustainability became a common industry refrain, he championed ethical governance, education, and inclusive development as essential to tourism’s future.To Solimar, Don was an inspiration, a steady source of encouragement, and a beloved mentor. He helped shape the people behind the company and supported us through every chapter. We remember him with deep gratitude, affection, and profound respect.
