Henri-Alphonse-Désiré Hervé was an innovative & productive French aero inventor. His work seems to have focused on LTA, and more particularly balloons, captive, as well as dirigibles, per se, with thorough attention given as well to all aspects navigation, stability, and so forth, as applied to these aircraft types.

On 12–13 September 1886 Hervé flew le National from Boulogne, France, to Yarmouth England, in a 24.5h flight which broke length records at the time.[1][2]

His table at the 1889 Exposition Universelle exhibited anchors, precision valves and instruments, braking systems, and diagrams of his ascents.[1]

Hervé was director of the Revue de l'aéronautique théorique et appliquée, 1888 to c. 1895.

He worked with comte Henry de La Vaulx and with him made some scientific studies aboard the Mediterranean in 1901 and the Mediterranean II in 1902.[2]

He experimented with the use of marine anchors for navigation, inventing the Hervé deviator.[2][3]

He used floating timbers in conjunction with sails, and succeeded in producing a deviation of about 70 degrees from the direction of the wind. Such "deviators" consist of a frame into which a number of straight or bent pieces of wood are fitted, one behind the other, somewhat after the fashion of a ladder. From the ends of this contrivance, ropes are taken to the balloon, by means of which the position of the rungs can be altered so as to present a variable angle to the course of the balloon. If the runs are placed parallel to the direction of flight, the balloon is subjected to a slight braking action, but the direction is of course unaffected. If the rungs are placed obliquely, the resistance, due to the water, is increased, and the balloon's course is deflected to that side on which the rope has been shortened"
