Abstract
The authors summarize the 44-year history of the Medical and Health Professionals’ Esperanto Group of Budapest, which was founded in 1969 in Hungary. The activities of the group can be divided into three periods: the early language learning, followed by a popular-science and a scientific era. In the current years of social-economic crisis the activities of the Group serve health and, according its broader interpretation, the physical, mental and social harmony by the help of Esperanto as a bridging language.
