Print taken from the ballooning magazine 'aerostation', showing Sadler's balloon being filled with gas and then ascending 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.
