Gauss's Law was formulated by
Carl Friedrich Gauss, a German mathematician and physicist, in the early 19th century, specifically in 1835. He is famous for his work in electromagnetism, and Gauss's Law is a fundamental law that describes the relationship between a static electric field and the electric charges that cause it.
Gauss's Law states that the electric flux through a closed surface is proportional to the charge enclosed within that surface. This is a key part of
Maxwell's equations, which govern electromagnetism.
Even though Gauss was the one to formalize it, the idea of electric flux and its connection to charge existed in different forms before him, but Gauss's contribution made the concept clear and mathematically rigorous.
