A list of his achievements in domestic affairs would not be complete without reference to his membership of the Australian Atomic Weapons Tests Safety Committee. But his success as a scientific administrator does not rest on domestic achievements alone. With characteristic realism, he recognised the essentially international nature of meteorological practice and devoted considerable attention to the affairs of the World Meteorological Organisation. At the Second Session of Regional Association V at Manila in 1958, he was elected President of the Region (South West Pacific) and this entitled him to a seat on the W.M.O. Executive Committee which, meeting annually in Geneva, virtually shapes the planning and philosophy of the Organisation. At the last Congress of W.M.O. (which occurs every fourth year) he played a very active part as Chairman of the Technical Committee.

Many telegrams and letters have been coming into the Bureau from all parts of the world emphasising the great loss caused by his untimely death and expressing sympathy for his widow and family. It would be impossible to reproduce all of them here, bit as examples of the many, we have taken leave to quote a letter from the Director of the Canadian Meteorological Service and one from a native observer in the highlands of New Guinea:

Dr. P. D. McTaggart-Cowan wrote

Len was a man that I greatly admired as a man, as a meteorologist and as a director of a large National Service. As a man, he had to an admirable degree the courage of his convictions, the forthrightness to state his views simply and directly and yet a sympathy and understanding of others and other people's views which very nicely tempered a vigorous philosophy with human kindness and understanding. The goals he set for himself were characteristically far higher than anyone else would have set for him.

As a meteorologist, he was understanding in the vision he had of the place of meteorology in this hectic modern world and of the Importance of tackling the scientific problems that the demands for service placed upon him on a broad, unselfish front.

As a director, he was outstanding. The growth of the Australian Meteorological Service under his guidance brought acclaim and commendation from all parts of the world. His strong leadership on many difficult matters within W.M.O. are a matter of record and acclamation.

World meteorology has lost a great man and a champion. The W.M.O, and particularly the Executive Committee, has lost one of its most effective leaders of thought and action; and I have lost a true friend whose counsel and philosophy I had sought and followed many times.

My deepest sympathy to his family in this sad moment of bereavement and to you and all your colleagues in the Meteorological Service of Australia.

From Mendi in the Southern Highlands District of New Guinea, Mr. Vai H. Gamu wrote as follows to the Officer-in-Charge of the Lae Meteorological Office:

It is with regret I hear the news of the death of the Director of Meteorology, Mr. L. J. Dwyer, in Melbourne yesterday evening. I do not know this important man personally, of course but, as a weather observer I find it is necessary for me to send to his good wife and family my personal sympathy through your office.

Immediately after this news was received I called for my family of four for a simple short prayer in honour for the late Mr. L. J. Dwyer. Respectfully, this was done.

In short, would you be kind enough to accept this letter of sympathy for submission to Melbourne for Mrs. Dwyer and family. In addition please accept of my wife's personal sympathy.
