Charles Green Spencer

His father was a solicitor and friend of the noted balloonist Charles Green, the United Kingdom's most famous balloonist of the 19th century, ascending with Green 27 times and soloing 40 times.

The firm for many years enjoyed a virtual monopoly in the manufacture of balloons and went on to be "manufacturers of aeronautical apparatus of every description" and specifically "balloons, airships and flying machines".

Later it was manufacturing "Salvus" parachutes with their promise of the "certainty of escape for aviators".

[2] He died on 4 June 1890 and is buried in the western side of Highgate Cemetery.

His namesake, Charles Green, was buried 20 years earlier on the eastern side of the same Cemetery.
