I knew of Dan Greenberg, while in graduate school, from Science Magazine and from reading his 1967 book. We met in person much later. He wrote as a political scientist and as a journalist. He was open, responsible, accurate, harsh, and witty. Although not everyone would agree, in his own peculiar way, Dan was one of the strongest advocates for science. Dan's critique helped shape my thinking about science policy. I took his views and stand as a challenge. I wanted to help improve connecting science and society.
More—much more—than anyone outside science and government, Dan was of most help while I served (1984-1990) as NSF assistant director for science and engineering education. All behind the scenes. Dan was a good man.
