'Benjamin Silliman' (
8 August 1779 –
24 November 1864) was an
American chemist, one of the first American professors of science (at
Yale University), and the first to distill petroleum.
Early Life
Silliman was born in North Stratford, now
Trumbull, Connecticut, at a family friend's home a few months after his mother fled for her life from their
Fairfield, Connecticut home ahead of 2,000 invading British troops that burned Fairfield center to the ground. The British forces had taken his father prisoner in May of 1779. His father was General
Gold Selleck Silliman and his mother was Mary Fish, widow of John Noyes.
Education
He was educated at
Yale, receiving an A.B. degree in 1796 and an A.M. in 1799. He studied law with
Simeon Baldwin from 1798 to 1799 and became a tutor at Yale from 1799 to 1802. He was admitted to the bar in 1802. President
Timothy Dwight IV of Yale proposed that he equip himself to teach in chemistry and natural history and accept a new professorship at the university. Silliman studied chemistry with Professor James Woodhouse in
Philadelphia, Pennsylvania and delivered his first lectures in chemistry at Yale in 1804. In 1805, he traveled to
Edinburgh for further study.
Career
Returning to
New Haven, he studied its
geology, and made a chemical analysis of the
meteorite that fell near Weston, Connecticut, publishing the first scientific account of any American meteorite. He lectured publicly at New Haven in 1808 and came to discover many of the constituent elements of many
minerals. The mineral
sillimanite was named after him. Upon the founding of the
Medical School, he also taught there as one of the founding faculty members. As professor emeritus, he delivered lectures at Yale on geology until 1855; in 1854, he became the first person to fractionate
petroleum by distillation.
Family
His first marriage was on
17 September 1809 to Harriet Trumbull, daughter of Connecticut governor
Jonathan Trumbull, Jr., who was the son of Governor
Jonathan Trumbull, Sr. of Connecticut, a hero of the
American Revolution. Silliman and his wife had four children: one daughter married Professor Oliver P. Hubbard, and another married Professor
James Dwight Dana. His son
Benjamin Silliman Jr., also a professor of chemistry at Yale, wrote a report that convinced investors to back
George Bissell's seminal search for oil. His second marriage was in 1851 to Mrs Sarah Isabella (McClellan) Webb, daughter of John McClellan. Silliman died at New Haven and is buried in
Grove Street Cemetery.
Legacy
Silliman was an opponent of slavery and a supporter of
Abraham Lincoln. He was a member of the
American Association for the Advancement of Science. He founded and edited the ''
American Journal of Science'', and was appointed one of the corporate members of the
National Academy of Sciences by the
United States Congress.
Silliman College, one of Yale's
residential colleges, is named for him, as is the mineral
Sillimanite.
