Way back in 1933, what Swiss-American astronomer first inferred the existence of dark matter?

Originally called the "missing mass," dark matter was first mentioned by Swiss-American astronomer Fritz Zwicky. In 1933, he discovered that the mass of the stars in the Coma cluster is only 1% of the mass required to keep the galaxies from escaping the cluster. This inferred the existence of dark matter, which is thought to make up 85% of matter in the universe.
