Isaac F. Stone
A Leader of U.S. Dye Industry in World War I
Reproduction of the biography of Isaac Frank (I. F.) Stone from A Souvenir of New York City, Old and New, New York Commercial,
1918, pp. 271-272:

The commonly accepted belief that the United States was entirely dependent upon Germany for colors has been exploded by I. Frank
Stone, President of the National Aniline & Chemical Co., and Vice-President of the Schoellkopf Aniline & Chemical Works. Mr. Stone,
who is an authority on dyes and chemicals, delivered an address before the National Silk Convention in Paterson, choosing as his
subject "The Manufacture of Aniline Dyes in America: the Progress Made and the Promise of the Future."  In upholding the quality of
the home product, Mr. Stone contended it was just as good as the foreign. He showed conclusively that American made colors are as
good and as fast as those made in Germany or any other foreign country and claimed that upon the conclusion of the war the bulk of
the trade will remain in the hands of the American manufacturers. Mr. Stone has spent his entire life in the chemical and dye
business and his complete knowledge of the trade makes his statement of great value.

He was born in Chicago, Ill., March 2, 1867, the son of Theodore and Mary S. (Owens) Stone. The ancestors were English, the
American branch being established at Guilford, Conn., by John Stone, as early as 1650. Mr. Stone was educated in the public schools
of Chicago and when but twenty years of age established himself in business in the Western city. In 1890 the firm of Stone & Ware
succeeded Mr. Stone, and seven years later the Stone & Ware Co. began business in New York City. This firm was highly successful
and Mr. Stone’s intense interest in everything pertaining to dyes and the thorough knowledge gained by his long experience led to his
selection, in 1900, as Vice-President of the Schoellkopf Aniline & Chemical Works.  In 1906 he was chosen head of the National
Aniline & Chemical Co., and since that period has been a most important factor in the chemical trade of the entire country. In addition
to these interests Mr. Stone is a Director of the Importers & Traders National Bank, the Contact Process Co., a member of the
Advisory Committee of the Metropolitan Bank and Rollin Chemical Co., a member of the Chamber of Commerce, the Board of Trade
and the Lotos,  Union League,  New York Athletic and City clubs. He was President of the Chemists' Club in 1910, the Heights Club in
1906 and Vice-President of the Drug & Chemical Club in 1909.  Mr. Stone was married in Chicago on June 5, 1889, to Miss Mary
Louise Peck. They have one daughter, Grace H., born March 12. 1892, and reside at Greenwich, Conn., where their  home, "Rock
Ridge," is one of the handsome houses of that picturesque locality.

The principal aniline and chemical companies located in New York City and the immediately contiguous territory were recently
amalgamated and are now operated by the National Aniline & Chemical Company, Inc., which took over the National Aniline &
Chemical Co., the Schoellkopf  Aniline & Chemical Works, Inc., W. Beckers Aniline & Chemical Works, Inc., the Benzol Products
Company and certain plants and properties of the General Chemical Company, the Barrett Company and the Semet-Solvay Company.
