Rollin King

Rollin W. King was a Texas entrepreneur and aviation enthusiast who operated a small commuter air service in Texas before conceiving the idea that became Southwest Airlines. King held a degree from Harvard Business School and brought the initial operational concept — connecting the Texas triangle of Dallas, Houston, and San Antonio with low-cost, high-frequency service — to Kelleher's attention in 1966. King served on Southwest's board for many years and was a key figure in the airline's early governance, though Kelleher became the more publicly prominent face of the company. King died on June 27, 2014.

Rollin King's contribution to Southwest Airlines is often overshadowed by Herb Kelleher's larger-than-life personality, but King was the conceptual originator of the airline. It was King who identified the market opportunity — the underserved triangle of Texas cities connected by road but not by affordable air — and who brought the sketch on a cocktail napkin that launched one of the most consequential business partnerships in American commercial history. King's background in small aviation operations gave him a practical understanding of aircraft economics that informed the early business plan, and his Harvard Business School training provided the analytical framework for evaluating the market opportunity. King stepped back from active management as Kelleher's profile grew, but his role in creating Southwest is properly understood as co-equal in the founding vision even if it was less central in the execution. His death in 2014, five years before Kelleher's, received relatively little public attention — a reflection of how thoroughly Kelleher had become identified with Southwest's brand in the public imagination.
