"Nehemiah Hawkins (1833 – January 15, 1928) was an American inventor, publisher and author (pen name Theodore Audel) born in Providence, Rhode Island. He started working with the G&C Merriam Company of Springfield, MA. In Chicago he established a magazine called Steam — soon sold and incorporated into Power — then moved to New York. He was survived by a son and two daughters. He wrote (or commissioned and published under his own name) many of the popular Audel's Guidespopular with engineers and craftsmen and published by Theodore Audel & Company of New York. He sometimes used the pseudonym William Rogers[6] (a likely reference to Roger Williams)." .
