Leonardo da Vinci designed ornithopter and flying machine concepts in the late 15th century, including early hang glider-like designs in his notebooks. While Otto Lilienthal built the first practical hang gliders in the 1890s, da Vinci's 15th-century conceptual designs qualify as 'first' in terms of design origination.

Benjamin Franklin invented bifocal lenses in the 1780s to address his own vision problems, allowing him to see both near and far with the same glasses. Alfred Nobel is known for dynamite, Edison for the light bulb and phonograph, and Diesel for the diesel engine.

Lewis E. Waterman invented the practical fountain pen in 1884 after losing a sale contract due to a leaking pen. He invented a reliable ink feed system using capillary action and gravity. John Loud designed an early ballpoint pen, Whittle invented the jet engine, and Macmillan is associated with early bicycle development.

John J. Loud patented an early ballpoint pen in 1888 for marking on rough surfaces like leather, but it was not commercially successful. The modern ballpoint pen was developed by Laszlo Biro in the 1930s. Alan Turing was a computer scientist, Otto is associated with the internal combustion engine, and Roger Bacon was a medieval philosopher.

Sir Frank Whittle invented the turbojet engine in the 1930s, patenting the design in 1930 and successfully demonstrating it in 1937. His invention revolutionized aviation by enabling jet-powered flight. Daimler developed early gasoline engines, Bacon was a medieval scholar, and Waterman invented the fountain pen.

Count Ferdinand von Zeppelin invented the rigid airship (the zeppelin) in the late 19th century, featuring a metal framework that maintained the airship's shape. Alan Turing was a computer scientist, Roger Bacon was a medieval philosopher, and Otto is associated with the internal combustion engine.

MIDI (Musical Instrument Digital Interface) was introduced in 1983 as a universal standard for connecting electronic musical instruments and computers. It allows instruments to communicate performance data (notes, velocity, timing) regardless of manufacturer.

Lewis Edson Waterman invented the practical fountain pen in 1884. He was an insurance salesman who lost a sale contract when his pen leaked, prompting him to invent a reliable pen with a capillary feed system. William Grove invented fuel cells, Kettering developed the electric starter and leaded gasoline, and George Fountain is not a historical inventor.

Paul Nipkow (1884), John Logie Baird (1920s), and Charles Jenkins (1920s) all contributed to the invention of mechanical television systems. Nipkow invented the scanning disk, Baird demonstrated the first working television system, and Jenkins developed early television transmission. Telephone, early warning systems, and electricity itself are different inventions.
