Although Werner von Siemens built the first electric elevator in 1880; this was merely an application (& marriage of) of pre-existing technologies, akin to Edison's "tinkering" inventions.

American Elisha Otis demonstrated a steam-powered freight elevator, equipped with a safety device* to prevent falling in case a supporting cable should break (the essential breakthrough), in 1853.

*"Improvement in Hoisting Apparatus."
Although Otis didn't actually invent the elevator, he invented the brake used in modern elevators. His brakes made skyscrapers a practical reality.

Hungarian Ányos Jedlik demonstrated the first experimental electric motors in in 1828, and British scientist William Sturgeon built the first “working” motor in 1832. In 1888, American emmigre Nikola Tesla invented the first practicable AC motor. Nobody from Thunder Bay has ever been demonstrably prominent in this field, though the City had Canada's first Electric Street railway..
