The GSD remembers Chien-Chung (Didi) Pei MArch ’72 who passed away on December 13th, 2023 at the age of 77. Didi was a distinguished member of the architectural community. His architectural firm, PEI Architects, “dedicated to design excellence in the creation of architecture that serves and enriches people and their environments” was founded in 1992 with his brother, Li Chung (Sandi) Pei MArch ’76. They both learned the craft of architecture from their father, world-renowned architect, I.M. Pei MArch ’46.

From PEI Architects on Didi Pei:

As 2023 draws to a close, our hearts are heavy with the loss of a remarkable leader and mentor, Chien Chung Pei, affectionately known as “Didi” to his family and friends. A distinguished architect, Didi’s journey began with academic excellence, graduating cum laude in Physics from Harvard College in 1968 and later attaining a Master’s Degree in Architecture from Harvard’s Graduate School of Design in 1972.

Steeped in the legacy of his father, the renowned architect I.M. Pei, Didi grew up immersed in the foundational principles of visionary design, unwavering commitment, and the highest professional standards. These early influences shaped his approach to architecture, guiding him in the creation of significant and enduring structures. Today, as we reflect on the passing of this extraordinary individual, we honor not only his impressive career but also the profound impact he had on the world of architecture and those fortunate enough to be touched by his wisdom and guidance.

Didi Pei blended science, art, and culture to create architectural landmarks that surpass physical form, leaving lasting imprints, serving function, and enhancing surroundings with beauty, purpose and standing the test of time. Through hands on involvement in all his design projects Didi embodied the core ideology of the firm he and his brother, Li Chung Pei, created, PEI Architects – “Respect for the past and responsiveness to the present in the pursuit of enduring architecture.”
