Sam H. Ham is a professor emeritus of communication psychology and conservation social sciences at the University of Idaho, USA. Sam’s work has taken him throughout the USA and Canada, and to nearly fifty other countries, where his approach to thematic communication is considered best practice in a wide variety of communication fields. Today, Sam’s thematic communication principles are put into daily practice by thousands of interpreters of cultural heritage and nature, as well as by museums, tour operators, zoos, botanical gardens, aquariums, national parks, and protected areas. Government bodies and private enterprises across the world have incorporated his theme-based principles into communication programs ranging from municipal sustainability and conservation education, to tourism marketing, philanthropy and interpretation of wine, beer, chocolate and art. His nearly 400 publications include the best-selling book, Environmental Interpretation—A Practical Guide for People with Big Ideas and Small Budgets, which was published in four languages. He also has edited six books on interpretation, storytelling and journalism for Fulcrum Publishing’s Applied Communication Series.
