Colour engraving by Havell after a drawing by E M Jones showing Sadler's balloon ascent from Merton Fields in Oxford. James Sadler was an ingenious inventor and became the first English aeronaut after his balloon ascent from Oxford on 4 October 1784. He made several more ascents before retiring from ballooning in 1785 and devoting his energies to improving the steam engine. He patented a rotary engine and experimented with steam-powered road vehicles. This ascent on 7 July 1810 to commemorate the installation of Lord Grenville as Chancellor of the University, marked Sadler's return to ballooning after a break of 25 years. Published by Bartlett of Bartlett & Newman, Oxford in 1816. Dimensions: 377mm x 241mm.
