who we are

In the autumn of 1930, Lambda Alpha was established at Northwestern University in Evanston, Illinois to help foster the study of land economics. The inspiration for Lambda Alpha was Professor Richard T. Ely (1854-1943), commonly called the “Father of Land Economics.”

The membership of Lambda Alpha includes outstanding individuals from many parts of the world who have distinguished themselves in all of the various disciplines and activities that relate to the use and re-use of land. These individuals include not only those who are involved in the ownership, management, regulation and conservation of land, but also those who are involved in its development, redevelopment and preservation.

The membership includes architects, engineers, real estate developers, planners, government officials, professors, bankers, attorneys, real estate consultants, and officials of organizations and national and international associations. The diversity of this membership provides an unusual reservoir of talent, knowledge and expertise to draw upon for educational programs and discussions. This reservoir in turn attracts others with talent, knowledge, and expertise to the educational activities of Lambda Alpha at both the international and Chapter level.

Connecting professionals.  Sharing knowledge.  Advancing best practices.
