James Glashier

Born in Rotherhithe, the son of a London watchmaker, Glaisher was a junior assistant at the Cambridge Observatory from 1833 to 1835 before moving to the Royal Observatory, Greenwich, where he served as Superintendent of the Department of Meteorology and Magnetism at Greenwich for 34 years.

In 1845, Glaisher published his dew point tables for the measurement of humidity. He was elected a Fellow of the Royal Society in June 1849.

[The Aeronauts](https://en.wikipedia.org/wiki/The_Aeronauts_(film))

The Aeronauts, released in 2019, includes a fictionalized account of the 5 September 1862 flight. The film depicts fictional pilot Amelia Wren, a composite of real-life female balloonists, joining Glaisher in an epic fight for survival while attempting to make discoveries in a gas balloon. The movie omits Henry Coxwell entirely. A report in The Daily Telegraph quotes Keith Moore, Head of Library at the Royal Society (Royal Society of London for Improving Natural Knowledge), as saying: "It’s a great shame that Henry isn’t portrayed because he performed very well and saved the life of a leading scientist".
