main points in researching about Donald Judd?

Answer 1

One of the kings of "Minimal art", back in the 60s, New York. I haven't paid much attention to such fads, since they rise and fall so easily, and the art is usually just downright unappealing. It is said that he wrote a few articles here and there, expounding on the hopelessly abstract.

His sculptures are mainly box constructions - cubes made of all different materials.
