Cornelis Easton was a Dutch journalist and amateur astronomer who wrote popular material on astronomy and climatology apart from giving lectures. As a journalist he worked with the Nieuwe Rotterdamsche Courant (1895–1906), Nieuws van den Dag (1906–1923), and Haagsche Post. In his first book, he was among the first to postulate a spiral structure for the Milky Way galaxy in which he located the Solar System on the edge. A street in Dordrecht is named after him.
