His father Benjamin Silliman Sr., also a famous Yale chemist, developed the process of fractional distillation that enabled the economical production of kerosene.
However, George Bissell, a lawyer from New York, his partner Jonathan Greenleaf Eveleth, and James Townsend, a New Haven bank president, had a revolutionary idea.
Yet Bissell and Eveleth, after realizing how flammable the liquid was, believed there was great money to be made in producing rock oil commercially, marketed as lamp fuel and such.
The immensely important main idea of his report was that distilled petroleum burned far brighter than any fuel on the market, except those that were far more expensive and less efficient.
Edwin Drake was in charge of drilling the well, and after many setbacks, generally revolving around the lack of money, he struck oil in quiet, rural, Titusville, Pennsylvania on August 27, 1859.
Almost equally important in Bissell's idea and Silliman's discovery was the use of rock oil for lubrication of the many moving parts in the mechanical age soon to come.
Silliman's wife, Susan Huldah Forbes, was a descendant of Joel Root, an early entrepreneur and supercargo on the sealing ship Huron.
