Williams Haynes was born in
Detroit, where his father, David Oliphant Haynes, was the
publisher of
The Pharmaceutical Era, as well as the president and the general manager of D. O. Haynes & Co. In 1896 D. O. Haynes established in
New York City the
New York Commercial as a daily newspaper on business. Williams Haynes worked as a reporter for the
New York Sun and as an editor for
Field and Fancy from 1906 to 1907. He enrolled in 1908 as a special student at
Johns Hopkins University, where he studied
economics,
biology, and
chemistry, but left in 1911 without a degree. He
married his first wife in June 1911. From 1911 to 1916 he was a contributor to magazines and newspapers and at various times visited Canada and Europe as a journalist. From 1914 to 1915 he was editor-in-chief of the Northampton, Massachusetts
Herald (a daily newspaper). In 1916 he became the editorial director of D. O. Haynes & Co. As editorial director he was responsible for the
chemical industry journal
Drug and Chemical Markets and in 1920 became the journal's publisher. In 1926 he split the journal into two journals:
Drugs and Cosmetics Industry and
Chemical Industries (later called
Chemical Week under the ownership of McGraw-Hill). In 1926 he also began publishing
Plastic Products (renamed
Modern Plastics, published from 1934 to 2004). In 1928 he established the
book series Chemical Who’s Who and was editor-in-chief of the series until 1951. In 1939 Haynes sold his interest in the trade journals in order to focus his efforts as an author and editor. He moved to a property near
Stonington in eastern Connecticut. The property, which had been in his family for several generations, had a
farmhouse built in 1750. As a journalist he contributed to
The Outlook,
The Nation,
The Dial,
Science, and
