Beatrice Tinsley was a British born - New Zealand astronomer and cosmologist whose research made fundamental contributions to the astronomical understanding of how galaxies evolve with time.

Tinsley completed pioneering theoretical studies of how populations of stars age and affect the observable qualities of galaxies.
