Edward Hazen

Edward Hazen was an American 19th-century author whose known works include The Panorama of Professions and Trades and Popular Technology; or, Professions and Trades. Title pages for those books also credit him with school-oriented works such as The Symbolical Spelling-Book, The Speller and Definer, and A Practical Grammar.

His books were designed to explain occupations, tools, and industries in clear, accessible language. That practical, educational approach suggests he wrote for general readers and younger learners as well as for anyone curious about how different kinds of work were done.

Reliable biographical details about his life appear to be scarce in the sources I could confirm, so it is safer to remember him mainly through the books he left behind: engaging surveys of trades and professions that offered readers a broad view of working life in the early to mid-1800s.
