In just now looking through the inventory of McCall's work, I noticed a resemblance in some ways to the work of Moebius. Not that either one borrowed from the other, but both of their technical draughtsmanship had similar sensibilities, resisting being too technical and pushing their imaginations beyond the obvious solutions. They both worked as visualizers for movies, designing the future as they went.
McCall is/was one of the higher pedestals in my hero hall of fame, as I'm sure he was to many people. I admire people who maintain a balance of humanities and sciences, not to mention having the spirit of exploration and adventure. As Michael Collins, of the Apollo 11 crew, said, "Robert McCall captures the essence of life in space, rather than just space itself."
I visited with McCall twice, once in 1982 at the Boulder Center for the Visual Arts, and at his home/studio in Paradise Valley. Each time he graciously talked shop with me, sharing his vision and technique, and allowing me to inspect the minute details of his work. My avid interest in space was fused with my avid interest in his work and he remains an inspiration to this day.
I'm going to post more of his work over the next couple of days as my little tribute.
He was an illustrator for the magazines, as well, such as this piece for a Boy's Life story of time travel.
He envisioned the 'near' future, such as a Mars colony . . .
