James Glaisher

James Glaisher was an English meteorologist, aeronaut, and astronomer, born on April 7, 1809, in Rotherhithe, London, and he died on February 7, 1903. He worked at the Royal Observatory, Greenwich, and became known for careful, systematic observations of the weather at a time when meteorology was still taking shape as a modern science.

He is especially remembered for his balloon flights with Henry Tracey Coxwell in the 1860s. These ascents were made to measure conditions high in the atmosphere, and they helped expand scientific understanding of temperature, humidity, and air pressure at great heights. One of the most famous flights in 1862 became extremely dangerous when Glaisher lost consciousness during the ascent.

Glaisher also played an important part in organizing and promoting meteorological research in Britain. Alongside his practical work in observation and data collection, he published widely and earned recognition as a Fellow of the Royal Society. His career captures a vivid moment in nineteenth-century science, when curiosity, discipline, and real physical courage often went hand in hand.
