Who was the first elected national president of AIID?

William R. Moore was the first elected national president of the American Institute of Interior Designers (AIID), which was established to advocate for interior design as a profession and to promote the interests of its practitioners. His leadership marked a significant moment in the history of the organization, as he played a key role in shaping the standards and future of interior design at a national level.

Moore's election as the first president reflects his influence and contributions to the field, highlighting the importance of having a structured professional organization to support interior designers during the mid-20th century. This development helped to establish interior design as a recognized profession, promoting education, ethical practice, and professional development among designers.

The other individuals listed, such as Florence Knoll, Frank Lloyd Wright, and Louis Kahn, are indeed iconic figures in the architecture and design fields, but they were not presidents of the AIID. Their contributions were significant in their respective areas, but the formal leadership within AIID is attributed to William R. Moore, marking him as a pivotal figure in the professional organization for interior designers.
