I am deeply saddened hearing about Amos' passing. He was a truly remarkable scientist with encyclopedic knowledge about proteins and their bulding blocks.

I first met Amos at my first scientific conference ever and was deeply impressed by his knowledge, his energy, and his never-ending flow of ideas. At that time, being a young student, I thought that this must be the way scientists are. Now, 30+ years later and having met many other scientists, I realized that Amos was truly unique.

The world will miss him.
