What sport did Edwin Hubble play at the University of Chicago?

Edwin Hubble played basketball at the University of Chicago. He was a forward on the Chicago Maroons men's basketball team during the 1908–09 season, while he was still an undergraduate.

Hubble was a gifted athlete long before he became famous for studying galaxies. At Chicago, he competed in basketball alongside his academic work and was listed on the team roster as Edwin Powell Hubble. His athletic ability was notable enough that sport remained an important part of his public biography.

The question can cause confusion because Hubble is overwhelmingly remembered as an astronomer, not a college athlete. He also played basketball at the University of Chicago during an era when college sports were already organized but had not yet developed the modern NCAA structure. His university career combined mathematics and science with serious competitive sport.
