HG has debt to Sir George Cayley; finding and highlighting the debt is invited in this topic thread.
He studied and experimented with important gliders before he presented material for the Nicholson's Journal of Natural Philosophy, Chemistry and the Arts. Exploring Cayley's glider work in that pre-Nicholson's period may be a delight. Then a solid study of Cayley's major first articles with an eye toward hang gliding promises students a rich experience. Tracing Cayley's influence on others that affected hang gliding is no small task, but one with rewards.

The three-part series on aerial navigation is available online in various ways, some more convenient than others. The direct Google reprint photo facsimile version.
===================================
One reprinter of part one of the series on aerial navigation made the following comment about Degen's flying effort:
1 Webmaster's note: Degen made a short "hop" off the ground with a pair of strapped-on wings. The published reports neglected to mention an important fact: Most of Degen's weight was supported by a balloon, so it is not surprising he was able to leave the ground. Fortunately this misleading report spurred Cayley to publish his thoughts on heavier-than-air flight. The British seem too reserved to publish their brilliant insights without some external prod.
