Document 2: Electric motor: After many other more or less successful attempts with relatively weak rotating and reciprocating apparatus the Prussian Moritz von Jacobi created the first real rotating electric motor in May 1834 that actually developed a remarkable mechanical output power. His motor set a world record which was improved only four years later in September 1838 by Jacobi himself. His second motor was powerful enough to drive a boat with 14 people across a wide river. It was not until 1839/40 that other developers worldwide managed to build motors of similar and later also of higher performance.

Document 8: Fan (machine): Between 1882 and 1886 Schuyler Wheeler invented a fan powered by electricity. It was commercially marketed by the American firm Crocker & Curtis electric motor company. In 1882, Philip Diehl developed the world's first electric ceiling fan. During this intense period of innovation, fans powered by alcohol, oil, or kerosene were common around the turn of the 20th century. In 1909, KDK of Japan pioneered the invention of mass - produced electric fans for home use. In the 1920s, industrial advances allowed steel fans to be mass - produced in different shapes, bringing fan prices down and allowing more homeowners to afford them. In the 1930s, the first art deco fan (the ``swan fan '') was designed. By the 1940s, Crompton Greaves of India became the world's largest manufacturer of electric ceiling fans mainly for sale in India, Asia and the Middle East.

His elevator ran faster and with larger loads than hydraulic or steam elevators, and 584 electric elevators were installed before Sprague sold his company to the Otis Elevator Company in 1895. Sprague also developed the idea and technology for multiple elevators in a single shaft.

Document 15: Marcelling: Accounts vary about the invention of the style. Some reports ascribe the invention of the technique to Marcel Grateau (1852 -- 1936), who invented it in 1872 (others say 1875). François Marcel Woelfflé, who later changed his name to François Marcel, was granted U.S. patents for implements for performing the technique: the first, U.S. patent 806386, entitled ``Curling - Iron '', was published in 1905, and the second, entitled`` Hair - Waving Iron'', for an electric version, under the name François Marcel, was published in 1918. There is also a 1936 obituary for Francois Marcel Grateau, with dates matching those of the first - named Marcel Grateau. Given the dates, and the coincidence of names, it is quite possible that they were all the same man.
