The International Making Cities Livable conference series was begun in 1985 by Dr. Henry L. Lennard, a Viennese medical sociologist, and Dr. Suzanne C. Lennard, an architectural researcher.

The conference series, study tours, and other events, bring together leaders from policy, practice and academia, to share effective tools and strategies, and to examine instructive case studies.
