I had the privilege of working for Professor Keyfitz from 1983 to 1989, when I left IIASA to move to the US. I am very saddened by his passing. He was not only the best in his field but also a wonderful, kind, and caring human being. My sincerest condolences to his family, some of whom I met in Baden, Austria.

What an affable and modest man, who at the same time was one of the two or three most creative demographers of the XXth century, ... and perhaps of all times. And I cannot think of any other who could draw so fruitfully on mathematics, economics and biology. I never read a paper by Nathan without learning something important. My sympathies to his family.

I have known Mr. Keyfitz as a remarkable scientist and a wonderful human being. He lived a beautiful and long life, but one has to feel very sorry that he is no longer with us. My thoughts are with his family and his closest friends. Most sincere condoleances.

I must offer my sincere and deepest sympathies. Professor Keyfitz as I used to adress him, will remain for ever in our minds and hearts. It seems to be just a week ago when Beatrice prepared a superb smoked salmon sandwich for our lunch as I learned the principles of the momentum of a population...They both knew how to teach us the important things of life and sciences!

I consider myself as one of his students; I did not talk to him or met him face to face, but will never forget him. I always remember the first time I was in the library and noticed his book “Applied mathematical demography” …. He will always remain in my mind

Nathan was one of the giants of demography. He was not only a leader in mathematical demography but also pioneered the application of demographic methods to several other fields. We at IIASA were privileged to have him as leader of our Population Program from 1983 (after retiring from Harvard) to 1991. Much of the work we are doing today – from applications of the multi-state model to probabilistic population projections to population-environment analysis – has its roots in Nathan’s creative ideas. We will always treasure his memory.

Please accept my deepest sympathies. Nathan was an outstanding personality and he will always remain in our hearts along with our memories.
Until very recently once in a while we were chatting with Nathan on Skype. I will miss our personal relationship a lot….
