Stanley Edward Spencer (1868–1906) was an early English aeronaut, famous for ballooning and parachuting in several countries, and later for building and flying an airship over London in 1902. Stanley's family had a history of flying: all his five siblings were also aeronauts, with Arthur and Percival the more well-known; his father Charles Green Spencer pioneered gliding and founded the balloon factory C.G. Spencer & Sons in London; and his grandfather had flown balloons with Charles Green since 1836. On 15 September 1898, Stanley piloted a hydrogen balloon for the meteorologist Arthur Berson in what was believed to be a record ascent to 27,500 feet. On 15 November 1899, Spencer ascended with John Mackenzie Bacon and Gertrude Bacon to observe the Leonid meteor shower from above the clouds
