Famous Inventors and Inventions

Early parachute testing caused numerous fatalities as inventors and adventurers jumped from towers, balloons, and aircraft using unproven designs. Franz Reichelt died in 1912 jumping from the Eiffel Tower. Ladders, race cars, and dynamite did cause deaths but not primarily during their invention testing phase - dynamite itself was designed to be safer than nitroglycerin.

Benjamin Franklin invented bifocal spectacles around 1784 to correct both near and far vision. He did not invent the radio (Marconi/Tesla), barometer (Torricelli), or hygrometer (multiple inventors). Franklin's other inventions include the lightning rod, Franklin stove, and the flexible urinary catheter.

Mary Kies became the first American woman to receive a patent in 1809 for her innovative method of weaving straw with silk to create hats. This was a significant milestone as it occurred decades before the Patent Office began systematically recording women's patents. Marjorie Joyner (hair care), Margaret Knight (paper bag machine), and Amanda Jones (canning) all received patents later in the 19th century.

Thomas Edison invented the phonograph in 1877, which is often conflated with the gramophone in quiz materials. The gramophone was actually invented by Emile Berliner in 1887, but Edison is the closest correct option among the choices provided. This is a common simplification in many quiz contexts.

Nicolaus Otto invented the first practical four-stroke internal combustion engine (the Otto cycle) in 1876. While the internal combustion engine has a complex history with multiple contributors including Lenoir and others, Otto is widely credited with the first commercially successful four-stroke engine in quiz contexts.

George Gamow was a key advocate of the Big Bang theory and coined the term itself, making major theoretical contributions. Einstein developed relativity theory, Penrose worked on black holes and singularity theorems, and Michael Skube is not associated with this theory.

Lewis Edson Waterman invented the practical fountain pen in 1884 after a leaking pen ruined an insurance contract, leading him to develop a reliable feed system. The other options are inventors of different technologies (grove: fuel cell, kettering: electric starter, fountain: not a real inventor).
