Henri Fabre (29 November 1882 – 30 June 1984) was a French aviator and the inventor of the first successful seaplane, the Fabre Hydravion.Henri Fabre was born into a prominent family of shipowners in the city of Marseille. He was educated in the Jesuit College of Marseilles where he undertook advanced studies in sciences.
He intensively studied aeroplane and propeller designs. He patented a system of flotation devices which he used when he succeeded in taking off from the surface of the Etang de Berre on 28 March 1910. On that day, he completed four consecutive flights, the longest about 600 metres. the Hydravion has survived and is displayed in the Musée de l'Air in Paris. Henri Fabre was soon contacted by Glenn Curtiss and Gabriel Voisin who used his invention to develop their own seaplanes.
As late as 1971, Fabre said he was still sailing his own boat single-handedly in Marseille harbour.He died at the age of 101 as one of the last living pioneers of human flight.

Robert J. "Bob" Parks (April 1, 1922 – June 3, 2011) was an American aerospace engineer and pioneer in the space program where he was intricately involved and/or directed for some of the most historic and important U.S. unmanned space missions. Over a 40-year tenure at the Jet Propulsion Laboratory (JPL/NASA), located in Pasadena, California, Parks’ impact was essential to helping the United States lead the world in space exploration. He served as Guidance Engineer for Explorer 1, the first successfully launched satellite by the United States. He directed the initial flyby missions to the Moon (Ranger 7, 8 and 9 Missions), the first soft landing on the Moon (Surveyor Lunar Lander), Earth's first successful mission to another planet (Mariner 2 to Venus) and initial missions to Mars, Saturn, Jupiter and Uranus.
Parks concluded his career as Deputy Director of the JPL/NASA and retired in 1987. Some of the awards he received for his work include the NASA Exceptional Service Medal (1967), the Stuart Ballantine Medal (1967), the Goddard Astronautics Award (1980) and the Caltech Distinguished Alumni Award in 1982.

Gabriel Voisin (5 February 1880 – 25 December 1973) was a French aviation pioneer and the creator of Europe's first manned, engine-powered, heavier-than-air aircraft capable of a sustained (1 km), circular, controlled flight, which was made by Henry Farman on 13 January 1908 near Paris, France. During World War I the company founded by Voisin became a major producer of military aircraft, notably the Voisin III. Subsequently, he switched to the design and production of luxury automobiles under the name Avions Voisin.

Jean Felix Piccard (January 28, 1884 in Basel, Switzerland – January 28, 1963 in Minneapolis, Minnesota), also known as Jean Piccard, was a Swiss-born American chemist, engineer, professor and high-altitude balloonist. He invented clustered high-altitude balloons, and with his wife Jeannette, the plastic balloon. Piccard's inventions and co-inventions are used in balloon flight, aircraft and spacecraft.
