Professor Koki Horikoshi
1932 - 2016

The International Society for Extremophiles mourns its honorary president Professor Koki Horikoshi and our thoughts are with Professor Horikoshi’s family and friends. The scientific community worldwide joins you all in this sad moment.

Professor Horikoshi was a marvelous person, a generous friend and inspiring collaborator. We have lost a pioneer of extremophiles research and a great microbiologist. Professor Horikoshi leaves a strong legacy of extremophiles research not only in Japan but world wide. He devoted his life to understand the secrets of the survival of microorganisms under extreme conditions. Many breakthroughs where achieved with his team at JAMSTEC especially with microorganisms that grow at high alkalinity and high pressure conditions. He is the discoverer of the alkaliphiles.

Professor Horikoshi was an excellent networker and communicator. He is the founder and president of the Japanese and International Societies of Extremophiles and the series of the International Conferences on Extremophiles. It is sad that Professor Horikoshi cannot attend the Kyoto Extremophiles Congress organized by Professor Atomi in September 2016. It was his wish to have this meeting in Japan.

Professor Horikoshi is (co-)author of a large number of research publications and books and is also the founding editor of the EXTREMOPHILES Journal (Springer). He was very keen to pass the knowledge on Extremophiles research to the young generation. His latest book „Extremophiles: where it all began“ is an excellent contribution describing autobiographically how research on Extremophiles started and developed.

Professor Horikoshi will always be remembered with great respect and admiration. The scientific community and especially the ISE owes him very much.
