T. L. Heath, the historian of mathematics, thought that the Greek mathematician Oenopides (ca. 440 BC) was the first to put compass and straightedge constructions above "neuseis". Hippocrates of Chios (ca. 430 BC) may have spread the idea that mathematicians should avoid "neuseis" whenever possible. He came from the same island as Oenopides, and who was—as far as we know—the first to write a systematically ordered geometry textbook. One hundred years after him, Euclid also said bad things about "neuseis" in his very influential textbook, "The Elements".
