In 1922, a pair of Columbia University sociologists named William Ogburn and Dorothy Thomas published a paper entitled “Are Inventions Inevitable?” which stated that Ogburn and Thomas discovered 148 examples of documented simultaneous invention. This phenomena occurred in 1876, when Alexander Graham Bell and Elisha Gray filed for a patent for the telephone on the same day with Bell’s unit having a separated listening and talking piece whilst Gray’s unit having a single listening and talking unit built into a conical structure. Other notable examples include Charles Darwin and Alfred Russel Wallace who came up with the Theory of Evolution simultaneously, Carl Scheele and Joseph Priestly who discovered oxygen at the same time, Isaac Newton and Gottfried Leibniz who discovered and developed calculus at the same time, Dmitri Mendeleev and Alexandre-Émile Béguyer de Chancourtois who discovered and developed the periodic table at the same time, and Orville and Wilbur Wright and Samuel Langley who invented the airplane during the same period of time. Knowing this, it would seem that the phenomena of simultaneous invention and discovery seems to be exceedingly common for human beings throughout history
