Kirkpatrick Macmillan is best known for inventing the first pedal bicycle. Synopsis Born on September 2, 1812, in Keir Mill, Thornhill, Scotland, Kirkpatrick Macmillan was a blacksmith who, in 1837, built a dandy horseâa kind of bicycle on which the rider pushes himself along with his feet. Three years later, Macmillan had applied a crank to his machine, making the world's first pedal cycle. The machine also included a wooden frame and iron-tired wheels. Macmillan's invention was never patented, and for many years it was credited to one of his imitators, Gavin Dalzell. Macmillan died in his hometown on January 26, 1878.
The big breakthrough, of course, was electricity. Nikola Tesla's development of alternating current motors made possible the invention of oscillating fans in the early 20 th century. And in 1902, a 25-year-old engineer from New York named Willis Carrier invented the first modern air-conditioning system.The mechanical unit, which sent air through water-cooled coils, was not aimed at human comfort, however; it was designed to control humidity in the printing plant where he worked.he big breakthrough, of course, was electricity.
