Walter Hunziker (1899-1974) was a Swiss professor who founded the Tourism Research Institute at the University of St. Gallen , co-developed the scientific study of tourism , co-founded the International Association of Experts Tourism Scientists (AIEST) and the International Institute of Glion . He is a director of the Swiss Tourism Federation, member of the Swiss Advisory Committee for Trade Policy, and author.  
Hunziker was born in Zurich on 27 Mar 1899  to Jakob Hunziker, but Walter Hunziker’s place of citizenship was Moosleerau , Aargau. In 1917, he completed a two-year primary commercial school ( Handelsschule ) in Zurich before receiving a Ph.D. in Economic Sciences from the University of Zurich in 1923.   His doctoral thesis was on the Swiss cotton industry, 1914- 1919. Hunziker was first employed by Swiss Natural Gas ( Schweizerischen Gaswerke ) and the Eidgenössische Bank , before becoming the business editor and subsequent business and publishing director of the Berner Tagblatt . 
Science of tourism
In March 1936, Hunziker was hired to be secretary of the Swiss Tourist Association and, on 23 Oct. 1937, appointed its director. In 1941, Hunziker was invited to graduate studies in tourism at the University of St. Gallen. Hunziker founded a Tourism Research Institute at the University of St. Gallen in Kurt Krapf at the University of Berne. The Institute is now known as the Institut für Öffentliche Dienstleistungen und Tourismus (Institute for Public Service and Tourism). In 1942, Hunziker collaborated with Krapf (director of the Bern Research Institute of Tourism) to publish the „Outline of the General Teaching of Tourism“ ( Grundriss der Allgemeinen Fremdenverkehrslehre ), which became the standard work for basic research in tourism.  As part of this text, Hunziker and Krapf developed one of the first broadly accepted definitions of „tourism“ ( Fremdenverkehr ), as translated from „Non-Residents of the United States. so far they are not leading to permanent residence and are not connected with any earning activity. “    A year later Hunziker published a book on the system of „scientific tourism research“ ( System und Hauptprobleme einer wissenschaftlichen Fremdenverkehrslehre ) in which he tries to establish a „completely new discipline“ as a branch of sociology ; however, the attempt failed. But Hunziker and Krapf continued to examine tourism not only from an economic perspective, but also from a sociological one. Hunziker did not want tourism to have a negative impact on the cultural values of the destination or the tourist.    In 1972, Dr. Hunziker defined the essential elements of tourism science as:
- understanding the nature of tourism;
- defining and explaining the various terms and concepts associated with tourism;
- developing tourism pedagogy that is practical and not just theoretical; and,
- addressing issues related to economic policy and business management.
Hunziker was an early advocate of the need to apply interdisciplinary scientific analysis to understand the highly diverse nature of tourism, develop a coherent tourism pedagogy, and use that analytical framework and training to solve problems associated with business management and economic policy. Although Hunziker was an economist by training, he rejected the earlier view of tourism as a subset of economics. Instead, Hunziker viewed tourism as a cultural phenomenon. As such, he has expanded to include aspects of sociology, psychology, history, geography, marketing and law and the understanding of how medicine and technology impacts tourism. 
In May 1959, at the second Congress of Social Tourism (Austria), Dr. Hunziker proposed the following definition: „Social tourism is a type of tourism practiced by low income groups, and is easily and easily rendered recognizable services „.  He viewed tourism as adding value to society by increasing understanding of other cultures and reducing xenophobia and isolationism.   For these reasons, Dr. Hunziker opined that governments should support and encourage social tourism. 
As a pragmatic implementation of social tourism, Walter Hunziker co-developed the concept of the Swiss travel savings fund ( Schweizerische Reisekasse or Reka), which helps low income families enjoy vacations.   Hunziker was president of REKA, 1939-1974.
Tourism institutes and associations
In 1951, Drs. Hunziker and Krapf founded the International Association of Scientific Tourism Experts (AIEST) in order to re-connect tourism researchers after World War II.   In 1962, Hunziker and Frederic Tissot co-founded the Glion International Institute .  Professor Hunziker was the founding president of the International Organization of Social Tourism and ran the organization from 1963 until his death in 1974. Consistent with Dr. Hunziker’s focus on social tourism, the aim of the OITS is to facilitate the development of social tourism in the international framework. on the subject of social tourism, as much as the cultural aspects and the economic and social consequences. “ Further, OITS continues to promote Dr. Hunziker’s interest in „access to leisure, holidays and tourism for the greatest number of people – youth, families, seniors and disabled people“ and „fair and sustainable tourism, ensuring profit for the host populations and respecting the natural and cultural heritage. “
