Born 7 Apr 1809; died 7 Feb 1903 at age 93. English meteorologist and aeronaut who, between 1862-66, mostly with Henry Tracey Coxwell, made balloon ascents, many of which were arranged by a committee of the British Association. The object was to carry out scientific observations such as the variation in temperature and humidity of the atmosphere at high elevations. On 5 Sep 1862, ascending from Wolverhampton, Glaisher and his companion attained the greatest height that had then been reached by a balloon carrying passengers.
