Benjamin Silliman, Jr. (1816-1885)
Silliman was an American chemist who followed after his father, Benjamin Silliman, Sr., as a professor at Yale University and editor of the American Journal of Science. Silliman discovered the chief uses of petroleum for the next fifty years and outlined the principle methods of preparing and purifying those products in his Report on Rock Oil, or Petroleum, from Venango County, Pennsylvania (1855), later republished in the American Chemist in July 1871.
