Abstract
History of the society from 1959 to 1994 was looked back, and some view points were summarized. Freeze-drying was introduced to my first study on purification of bacterial antigen in 1955. Since then my working and research were concerned with dried biological pharmaceutical products, trials on various kind of freeze-drying machines and development of apparatus for measurement of residual moisture content in dried products. The Japanese Society for Research of Freezing and Drying was established by Professor Tokio Nei, Institute of Low Temperature Sciences, Hokkaido University, in 1955. The first reorganization by the committee report on future plan (Chairman, Prof. T. Nei) in 1968 activated the society. Prof. T. Nei contributed to the society, and his strong impact is shown in the follows: establishment of the society, the first reorganization, president for 6 years, the 15th Cryobiology Meeting in Tokyo, Japan-U.S.A. Joint Seminar, publication of papers and books, encouragement for younger researchers and so on. In 1994, by progress of research field, the second reorganization of the Society was conducted by two presidents, Mitsuo Takano and Kazuhide Yamasato. Society name is changed to "Japanese Society for Cryobiology and Cryotechnology".
