Donald Figer is an American astronomer. He works at the Rochester Institute of Technology, where he is a Professor, and Director of the Center for Detectors. He claims that 150 solar masses is the upper limit for stars. By using the Hubble Space Telescope, he observed approximately one thousand stars in a young star cluster, the Arches Cluster, which is near the center of the Milky Way. None of the stars surpassed this limit.

He also identified the Pistol Star as one of the most massive in the Universe.
