"Here, in approximately one hundred pages is the simple, un-adorned, and statistic-less story of an average Americanindustry. It began in a modest way in 1850, when a distinguished Baltimore chemist, Dr. Richard A. Tilghman, who, while studying in England, discovered two important chemical processes, returned to the United States and obtained patents for them. The patents covered a process for manufacturing caustic soda ash, and chlorine-bearing compounds, such as bleaching powder. It was known as 'TheStrontiaProcess'." [from a book review by John W.
