The public mandate for a building that would harmonize with the site was foremost in the minds of the selection committee when it began searching for an architect. Seven member universities of the University Corporation for Atmospheric Research (UCAR), NCAR's parent organization, had schools of architecture, and the deans of these departments formed the committee, which began by drawing up an ambitious slate of six nationally known architects in May of 1961. NCAR staff members were heavily involved in the interview process, which culminated in the unanimous selection of I.M. Pei two months later. It was a decision that was to profoundly affect the futures of both Pei and of NCAR.

I.M. Pei has become one of the foremost architects of our time, creating designs that have altered the cityscapes of the United States, Europe, and Asia. However, at the time, he was not an obvious choice for the NCAR commission. While widely respected, he had made his reputation as a designer of large urban renewal projects—he had never tackled a project set off from an urban setting. Prophetically, the NCAR selection team saw this inexperience as an advantage.

In addition, Pei's reputation as a man who dealt easily with clients, his charm and sensitivity, his imagination in design, his experience within tight budgetary constraints (notably with the use of structural concrete) all contributed to his selection. For his part, Pei was openly eager to tackle the creative demands of the NCAR assignment. As both the NCAR staff and Pei had hoped, the Mesa Laboratory was to mark a break through that was to change the direction of the architect's career. 

Pei was born in Canton, China, in 1917, and moved to the United States in 1935 to study engineering and architecture at the Massachusetts Institute of Technology and the Harvard School of Design. Pei studied under famous Bauhaus designers Walter Gropius and Marcel Breuer. Though not a "functionalist," Pei does acknowledge Breuer's influence on his strong interest in "light, texture, and shadow"-- all very apparent in the NCAR design.

Pei and NCAR founding director Walt Roberts became friends during the Mesa Laboratory project and remained so long after the building was completed. “How he would talk about the weather!” said Pei, remembering the late Dr. Roberts, “It was absolutely fascinating. He would look up at a clear blue sky and say that it was going to rain, and when – and then it did!”
