1869–1958
A chemist and soil scientist rather than a literary celebrity, he wrote practical early-20th-century books about how soils, minerals, and plant nutrition work. His work helped explain the chemistry behind agriculture in a clear, applied way.

by Frank K. (Frank Kenneth) Cameron
Frank Kenneth Cameron was an American chemist and soil scientist born in 1869 and died in 1958. Sources from the Smithsonian Institution describe him as a chemist who worked for the U.S. Bureau of Soils and later became a professor at the University of North Carolina.
He is best remembered for technical works on soil chemistry and plant growth, including The Soil Solution: The Nutrient Medium for Plant Growth. Archive records also connect his name with studies of alkali soils, mineral constituents in soil solutions, fertilizer resources, and potash from kelp, showing the wide range of his scientific interests.
For listeners coming to his work today, the appeal is its window into an earlier era of agricultural science. His writing reflects a time when researchers were trying to understand farming at the chemical level and turn that knowledge into practical guidance.
