BACK TO NEWTON: A Challenge to Einstein's Theory of Relativity.
New York: G. E. Stechert & Co., 1936. SIGNED hardcover first edition - In this book, this Russian-born engineer and pioneer of helicopter flight not only attacked Albert Einstein's theory of relativity but the whole world of contemporary academics "who are utterly unable to acquaint themselves with the subject". Einstein personally refuted de Bothezat's claim at a public lecture given by de Bothezat at Princeton in 1935. (Although this book was not published until 1936, there is a notation that the first draft of this essay was written in French in 1932 and an even earlier version was published in a journal in 1928). While this book might have failed at proving that Einstein's theory was a fallacy, de Bouthezat had an interesting and varied career. In 1921, he was hired by the US Army Flying Services to build a prototype helicopter - which he did at Wright Field. This quadrotor helicopter (or de Bouthezat helicopter) flew several times in 1922, only to have the Army lose interest in the project, although in 1938 de Bouthezat returned to helicopters and founded the Helicopter Corporation of America.
