William Zinsser Still Teaching Writing at 90

In newsrooms, publishing houses and wherever the labor centers on honing sentences and paragraphs, you are almost certain to find among the reference works a classic guide to nonfiction writing called On Writing Well, by William Zinsser. The former Yale University professor is still teaching at 90, holding one-on-one counseling sessions for writers at his Upper East Side apartment in New York City even though he can no longer see. "People read with their ears, whether they know it or not," he said.
