Widely acclaimed by his colleagues, co-workers, and patients, Dr. Heinrich Meng celebrated this summer his seventieth birthday. Dr. Meng was highly thought of by Freud and became closely associated with the late Dr. Paul Federn, with whom he edited well-known encyclopedias on

general medicine as well as on psycho-analysis. To-day Dr. Meng is considered the outstanding representative of psycho-analysis in the German-speaking countries of Europe. Dr. E. Blum, one of the oldest members of the Swiss Psycho-Analytical Society, expresses his and his colleagues' appreciation of Dr. Meng in a special issue of the Swiss periodical, Der Psychologe.
