Fred Lawrence Whipple (1906–2004) was an American astronomer known for his significant contributions to the study of comets and the physics of planetary atmospheres. He is best known for developing the "Whipple prism" method for studying comet nuclei and for his work on the "dirty snowball" model of comets, which suggests that comets are composed of ice and dust. Whipple also made contributions to the understanding of meteoroids and their interaction with Earth’s atmosphere.
