James Sadler (balloonist)
Sadler was the second person to make a balloon ascent in England, very soon after the Tuscan Vincent Lunardi's flight on 15 September 1784 in the grounds of the Honourable Artillery Company at Moorfields. Sadler made his ascent during the month after on 4 October 1784 from Christ Church Meadow, Oxford. The balloon rose to about 3,600 feet and landed near Woodeaton, around six miles away. His second ascent on 12 November, this time in a hydrogen-filled balloon, reached Aylesbury in Buckinghamshire after a twenty-minute flight. In May of the following year he took off near Moulsey Hurst, Surrey, accompanied by W. Wyndham MP, hoping to reach France, but in fact descending in the Thames Estuary, and thus failing to repeat the earlier exploit of Jean-Pierre Blanchard and his passenger. Sadler made two further ascents in May 1785, the first of which was from a field behind a gentleman's garden on the site of what is now Balloon Street in Manchester. On this flight he was accompanied by a cat and landed in Radcliffe. On his second ascent he travelled alone and having risen to 13,000 ft. travelled 50 miles before landing near Pontefract, West Yorkshire. On this occasion, he sustained bad injuries after being dragged for around 2 miles by the balloon, which eventually threw him clear before taking off again empty.
He was appointed Chemist in 1796 in the newly created Naval Works Department under Sir Samuel Bentham. Although the post was only abolished in 1807, he had major disagreements with Bentham and carried out few works. His most important invention was that of the table steam engine.
He resumed his ballooning activities although he was devastated by the death of his younger son, Windham, in a ballooning accident in 1824.
