Answer Key
Alexander Graham Bell was awarded the first patent for the telephone in 1876, though others like Elisha Gray were working on similar devices.
Gutenberg's movable-type printing press made books affordable and accessible, sparking a revolution in literacy and knowledge sharing.
Tim Berners-Lee, a British scientist at CERN, invented the World Wide Web, creating HTML, URLs, and HTTP.
In 1945, Percy Spencer was working with radar equipment when he noticed a chocolate bar had melted, leading to the invention of the microwave oven.
While others created earlier versions, Thomas Edison developed the first commercially practical incandescent light bulb in 1879.
Orville and Wilbur Wright achieved the first sustained, controlled, powered flight on December 17, 1903, at Kitty Hawk, North Carolina.
Fleming discovered penicillin when he noticed mold killing bacteria in a petri dish, leading to the first antibiotic and saving millions of lives.
Eli Whitney's cotton gin mechanized the process of separating cotton fibers from seeds, dramatically increasing cotton production.
Tesla championed alternating current (AC) electrical systems, which proved more efficient for long-distance power transmission than Edison's DC system.
Edward Jenner created the first vaccine in 1796 using cowpox to immunize against smallpox, pioneering the field of immunology.
Samuel Morse co-developed the electric telegraph and created Morse code, revolutionizing long-distance communication.
