In some families, passion and creativity seems to be passed from generation to generation. For these five legendary architectural dynasties, the talent to construct some of the world’s most iconic structures just happens to run in the family. From the international landmarks of I. M. Pei and his two sons, Chieng Chun and Li Chung, to the monumental works by design duo Eliel and Eero Saarinen, it’s clear that these renowned architects have left their mark around the world. With Father’s Day just around the corner, we take a look at some of architecture’s founding fathers, and the sons that continue to follow in their footsteps.

One of Eero Saarinen's most influential structures, the St. Louis Gateway Arch.

Eliel and Eero Saarinen Sharing the same birthday (August 20) as well as an eye for design, father and son were both awarded Gold Medals from the American Institute of Architects for their contributions to U.S. architecture. Before emigrating to America from Finland, Eliel constructed the Helsinki Central Railway Station. He later designed and became president of the Cranbrook Academy of Art in Bloomfield Hills, Michigan, where son Eero was a student. Eero’s own design feats include the St. Louis Gateway Arch , the JFK International Airport, and iconic furnishings for Knoll.
