Eli Whitney (December 8, 1765 – January 8, 1825) was an American inventor best known for inventing the cotton gin. This was one of the key inventions of the Industrial Revolution and shaped the economy of the antebellum South. Whitney’s invention made short staple cotton into a profitable crop, which strengthened the economic foundation of slavery.
Despite the social and economic impact of his invention, Whitney lost his profits in legal battles over patent infringement, closed his business and nearly filed for bankruptcy.
Karl Friedrich Benz, sometimes spelled as Carl, (25 November 1844 – 4 April 1929) was a German engine designer and automobile engineer, generally regarded as the inventor of the petrol-powered automobile and pioneering founder of the automobile manufacturer, Mercedes-Benz.
In 1800, Napoleon Bonaparte offered an award of 12,000 francs to anyone who could devise a practical method for food preservation for armies on the march; he is widely reported as saying “An army marches on its stomach”. After some 14 or 15 years of experiment, Appert submitted his invention and won the prize in 1810. The following year, Appert published L’Art de conserver les substances animales et végétales (or The Art of Preserving Animal and Vegetable Substancess). This was the first cookbook of its kind on modern food preservation methods.
Charles-Édouard Jeanneret-Gris, who chose to be known as Le Corbusier (October 6, 1887 – August 27, 1965), was a Swiss-French architect, designer, urbanist, writer and also painter, who is famous for being one of the pioneers of what now is called Modern architecture or the International Style.He was born in Switzerland, but became a French citizen in his 30s.

Thomas Hunt Morgan – American geneticist and first Nobel Prize winner in the field of genetics.
Thomas Hunt Morgan (September 25, 1866 – December 4, 1945) was an American geneticist and embryologist. Morgan received his PhD from Johns Hopkins University in 1890 and researched embryology during his tenure at Bryn Mawr. Following the rediscovery of Mendelian inheritance in 1900, Morgan’s research moved to the study of mutation in the fruit fly Drosophila melanogaster. In his famous Fly Room at Columbia University Morgan was able to demonstrate that genes are carried on chromosomes and are the mechanical basis of heredity. These discoveries formed the basis of the modern science of genetics. When he was awarded the Nobel Prize in Physiology or Medicine in 1933 he was the first person awarded the Prize in genetics, for his discoveries concerning the role played by the chromosome in heredity.
John Loudon McAdam (21 September 1756 – 26 November 1836) was a Scottish engineer and road-builder. He invented a new process, “macadamisation“, for building roads with a smooth hard surface that would be more durable and less muddy than soil-based tracks.
Modern road construction still reflects McAdam’s influence. Of subsequent improvements, the most significant was the introduction of tar (originally coal tar) to bind the road surface’s stones together – “tarmac” (for Tar Macadam) – followed later by the use of hot-laid tarred aggregate or tar-sprayed chippings to create better road metalling. More recently, oil-based asphalt laid on reinforced concrete has become a major road surface, but its use of granite or limestone chippings still recalls McAdam’s innovation.
Oliver Evans (13 September 1755 – 15 April 1819) was an American inventor. Evans was born in Newport, Delaware to a family of Welsh settlers. At the age of 14 he was apprenticed to a wheelwright.
Evans’ first invention was in 1777, when he designed a machine for making card teeth for cardingwool. He went into business with his brothers and produced a number of improvements in the flour milling industry. His most important invention was an automated grist mill which operated continuously through the use of bulk material handling devices including bucket elevators, conveyor belts, and Archimedean screws. Evans described this invention in The Young Mill-wright and Millers’ Guide. He patented this invention in a few states and, when the US patent system was established, in the federal patent system. Evans devoted a great deal of his time to patents, patent extensions, and enforcement of his patents.
In 1792 he moved to Philadelphia, Pennsylvania, where he produced an improved high-pressure steam engine — his second most important invention. For some years he contemplated the idea of applying steam power to wagons. He was granted a patent for a steam-carriage design in 1789, but did not produce a working example of such a machine until over a decade later. (See below on his Oruktor Amphibolos). Part of his difficulties was a failure to get financial backing. After lack of support in his native land, in 1794 he sent copies of some his designs to Great Britain in an attempt to interest investors there.
As Evans designed a refrigeration machine which ran on vapor in 1805, he is often called the inventor of the refrigerator, although he never built one. (His design was modified by Jacob Perkins, who obtained the first patent for a refrigerating machine in 1834).
