LESTER KAUFMAN is the author of The Blue Book of Grammar and Punctuation and publisher of GrammarBook.com. A lifelong public servant, he served first in the Peace Corps, and eventually completed the final years of his federal career with the U.S. Environmental Protection Agency. He married Jane Straus in 1987. After his retirement from the EPA, Kaufman began working with Jane on The Blue Book of Grammar and Punctuation and the GrammarBook.com website.

Following Jane Straus's untimely passing in early 2011, Kaufman assumed the role of author of new editions of The Blue Book of Grammar and Punctuation and continued the publication of GrammarBook.com, which features an informative and entertaining weekly newsletter that encourages readers to ask grammar questions and offer their views on the state of twenty-first-century English.
