About the Author
Norman Lewis was an author, grammarian, lexicographer, and etymologist. Lewis was a leading authority on
English-language skills, whose bestselling 30 Days to a More Powerful Vocabulary published by Pocket Books in 1971
promised to teach readers to improve their skills in fifteen minutes a day. He started his teaching career at New York
University and the City College of New York. From 1964 to 1995, he taught English—including grammar, etymology, and
vocabulary—at Rio Hondo College, a two-year community college in Whittier, California. For more than a decade, he was
also the chairman of Rio Hondo’s communications department.
