Which Yale professor analyzed Rock Oil as an illuminant in 1855?

• A. Dr. Benjamin Silliman Jr.
• B. Dr. Benjamin Silliman Sr.
• C. Dr. James D. Smith
• D. Dr. Samuel W. Langley

Answer: (A)

Testing rock oil as a lighting fuel was a pivotal moment in the mid-1800s. Benjamin Silliman Jr., a Yale chemistry professor, conducted early experiments on rock oil (petroleum) around 1855, examining how it burned, the brightness it produced, and its potential advantages over whale oil. His practical assessments showed that petroleum could serve as a viable illuminant, helping to shift lighting away from whale oil and toward petroleum-based fuels that would later evolve into kerosene lamps. He belonged to a prominent Yale scientific family, the son of Benjamin Silliman Sr., who was influential in science but not the specific 1855 illuminant analysis. The other individuals listed are associated with different fields or time periods and do not fit this particular Yale 1855 analysis.
