Short Summary
Henry Cavendish was an eminent British natural philosopher, chemist, and physicist, most renowned for his discovery of hydrogen, which he termed "inflammable air." His meticulous experiments and innovative methods significantly advanced the understanding of gases and electricity. Despite his reclusive nature, which kept much of his work unpublished during his lifetime, Cavendish's contributions to science laid foundational knowledge that would be built upon by future generations, securing his place as one of the key figures in the scientific revolution of the 18th century.
Early Life & Education
Born on October 10, 1731, in Nice, which was then part of the Kingdom of Sardinia, Henry Cavendish came from the illustrious Cavendish family, known for its political influence and wealth. His father, Lord Charles Cavendish, was a distinguished member of the Royal Society, which likely fostered Henry’s early interest in science. He was educated at the prestigious Hackney Academy in London, where he excelled in mathematics and the sciences. He later attended Peterhouse, Cambridge, though he left without earning a degree. This formative period was crucial in shaping his methodical and analytical approach to scientific inquiry.
Career Highlights
Cavendish's career was marked by groundbreaking experiments and meticulous research. In 1766, he published a paper detailing the properties of hydrogen, identifying it as a distinct substance. He conducted pioneering investigations into the density of the Earth, commonly known as the Cavendish Experiment, which was pivotal in determining the Earth’s mass. His extensive study of electricity predated the work of later scientists like James Clerk Maxwell. Cavendish often worked in seclusion, with much of his research remaining unpublished until after his death, when James Clerk Maxwell compiled and published his electrical experiments.
