It's difficult to say definitively which scientists did not study the properties of light, as the study of light has been a cornerstone of science for centuries. Many scientists across various disciplines have contributed to our understanding of light.

However, some notable figures whose primary focus was not on light, but who made significant contributions to our understanding of its properties include:

* Isaac Newton: While famous for his work on gravity and calculus, Newton also made significant contributions to optics. His experiments with prisms and the discovery of the spectrum of light were crucial in understanding its composition and properties.

* Albert Einstein: His theory of relativity provided a new framework for understanding the nature of light and its relationship to space and time.

* James Clerk Maxwell: His formulation of electromagnetic theory unified electricity, magnetism, and light, demonstrating their interconnectedness.

It's important to remember that even scientists focusing on other areas of science likely encountered light and its properties in their work, whether directly or indirectly.

Therefore, saying which scientists did not study light is challenging, as nearly all scientists, to some extent, are involved in understanding the world around us, and light is a fundamental part of that world.
