In memoriam

In Memoriam Dr. Alec Eden

Dr. Alec Eden - 1935-2011

It is unusual to write a celebration of life of a businessman to be published in a newsletter of a scientific medical society. But Dr. Alec Eden, born in Sussex , England was an outstanding and stimulating personality, scientist and businessman. His importance for our society, the NSRG, lies in his role as chief executive of the Eden Medizinische Elektronik (EME) from 1981 to 1992. Due to his inexhaustible energy, he was responsible for a considerable part of the worldwide dissemination and acceptance of Transcranial Doppler Sonography (TCD). TCD has become a real breakthrough for Neurosonology. It was primarily made possible by the Norwegian Rune Aaslid, who developed the first Transcranial Doppler device in the neurosurgical clinic of Prof. Nornes in Oslo and later Bern Switzerland. The development of extracranial Doppler sonography in the decade before was slow and had to fight for acceptance in the medical community. TCD on the other hand spread like wildfire from Europe to North America and to the Far East. Constantly travelling through the world Dr. Eden brought together many researcher, sponsored congresses and organized meetings himself (The Web and Email were not yet available). Dr. Eden was fascinated by the ultrasonic methods, especially TCD and its neurologic as well neurosurgical applications. His enthusiasm was authentic. He published 15 papers in scientific journals or chapters in books about Doppler sonography as first author or co-author. In addition he developed interest in Christian Doppler, the man, his research, his family and his life in Salzburg and Prague. He described special aspects of Doppler’s life in several Journals such as Ultrasound in Med & Biol and published the book: “The search for Christian Doppler” 1992 by Springer Verlag/ Wien including many documents from the archives. Alec Eden - The Search For Christian DopplerAs a consequence he was appointed president of the Christian Doppler foundation, Salzburg. Dr. Eden received numerous awards from universities and institutes, among them Winston Salem; Birmingham, Alabama; Peking; Salzburg and Prague. He was honored by the Japan Academy of Neurosonology and the American Society of Neuroimaging. He received the Order of Merit in Gold , Republic of Austria. All this is indeed unusual for a businessman.

Dr. Eden’s activities were not limited to medical aspects. He promoted art exhibitions and was engaged in supporting problems in the third world through UNICEF and Rotary international.

Dr. Eden passed away following a severe stroke in February of this year. He left behind his wife Frauke, two children and four grandchildren. Our sympathy goes to his family.

Professor Furuhata was a great scientist and a great man. He will stay for new generations and for all of us, as a prototype of scientist, teacher and humanist, contributing to the advance of medicine and the world's heritage.

We will all miss him.

His notable contribution to the field of neurosonology and his able leadership in experimental sonothrombolysis research won him respect both nationally and internationally. We shall always remember him, not only as a scientist but as a friend and his humanity. We offer our sincere thanks to all those who showed him kindness during his lifetime.

Toshiyuki Shiogai, M.D., Ph. D.



I mourn this excellent man, outstanding scientist and gentleman and I will miss him for a very long time.

G. Paolo Anzola



Pr Hiroshi Furuhata was a great scientist and a gentleman. We will miss him.

Hiroshi was a great scientist. He made a great contribution in the knowledge on basic research of sonothrombolysis. He was a charismatic mentor of many young neurologistis in Japan and an endless souce of ideas and projects, but most importantly, he was a very good friend.

Carlos Molina Cateriano



This is a great loss of a friend, a peer and a wonderful human being to those of us who got to know him closely and enjoyed his company for many years. I'm very sad will miss him a lot!

I wonder if Jikei University would consider naming the Biomedical Engineering Laboratory in his name since he accomplished so much and trained many neurosurgeons and scientists over years there. Best wishes to all and may he rest in peace!

Andrei V. Alexandrov, MD



Professor Furuhata was not only the pioneer of our discipline but a a kind hearted  man who touched everyone's life - he will be sadly missed. God bless his soul! The ESNCH will commemorate Professor Furuhata.

This are very bad news and we are in deep regret. I was very glad to know him and to have him at the ESNCH meeting in Düsseldorf as an important scientific as well as friendly colleque and gentleman. We will miss him.

Mario Siebler



Our "neurosonology world" has lost one of great pioneers and researchers in the area of ultrasound. I am sure that his colleagues and many young Japanese sonographers will continue his path. My sympathies to his family, friends and colleagues.

Alexander Razumovsky, PhD, FAHA



I would like to express to you, to his colleagues and especially to his family, my deepest sympathy on the loss of Prof Furuhata. He was a pioneer in this field and has brought tremendous contributions.

Fabienne Perren, MD



It is indeed a very sad to hear this bad news. Professor Furuhata was a great scientist and a leader in the world of neurosonology. He was also a great teacher for many of us in Asia and especially in Japan. Everyone in the field of neurosonology will miss him a lot. Please kindly send my condolence to his family.
