Herman Zanstra (November 3, 1894– October 2, 1972) was a Dutch astronomer. He wrote a famous paper, An Application of the Quantum Theory to the Luminosity of Diffuse Nebulae, which for the first time provided a quantitative method (the "Zanstra method") for understanding the luminosity of nebulas and comets.
