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 Greenwich Observatories, where he served as Superintendent of the Department of Meteorology and Magnetism at Greenwich for thirty-four years.
He is most famous, however, as a pioneering balloonist. Between 1862 and 1866, usually with Henry Tracey Coxwell as his co-pilot, Glaisher made numerous ascents in order to measure the temperature and humidity of the atmosphere at its highest levels. His ascent on 5 September 1862 broke the world record for altitude, but he passed out around 8,800 metres before a reading could be taken. One of the pigeons making the trip with him died. Estimates suggest that he rose to more than 9,500 metres and as much as 10,900 metres above sea-level. 
He had married in 1843 Cecilia Louisa, a daughter of Henry Belville, Assistant at the Royal Observatory, Greenwich. James and Cecilia Glaisher had three children, including the mathematician James Whitbread Lee Glaisher (1848–1928).
