Jean Felix Piccard, 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.

Jeannette Ridlon Piccard was an American high-altitude balloonist, and in later life an Episcopal priest. She held the women's altitude record for nearly three decades, and according to several contemporaneous accounts was regarded as the first woman in space.
