History
- 1839 Earnshaw's theorem showed electrostatic levitation was impossible, later theorem was extended to magnetostatic levitation by others
- 1912 Emile Bachelet awarded a patent in March 1912 for his “levitating transmitting apparatus” (patent no. 1,020,942) for electromagnetic suspension system
- 1933 Superdiamagnetism Walter Meissner and Robert Ochsenfeld (the Meissner effect)
- 1934 Hermann Kemper “monorail vehicle with no wheels attached.” Reich Patent number 643316
- 1939 Braunbeck’s extension showed that magnetic levitation is possible with diamagnetic materials
- 1939 Bedford, Peer, and Tonks aluminum plate placed on two concentric cylindrical coils shows 6-axis stable levitation.
- 1961 James R. Powell and BNL colleague Gordon Danby electrodynamic levitation using superconducting magnets
- 1970s Spin stabilized magnetic levitation Roy M. Harrigan
- 1974 Magnetic river Eric Laithwaite and others

Famous quotes containing the word history:
“... in a history of spiritual rupture, a social compact built on fantasy and collective secrets, poetry becomes more necessary than ever: it keeps the underground aquifers flowing; it is the liquid voice that can wear through stone.”
—Adrienne Rich (b. 1929)
“There is no example in history of a revolutionary movement involving such gigantic masses being so bloodless.”
—Leon Trotsky (1879–1940)
“When the history of this period is written, [William Jennings] Bryan will stand out as one of the most remarkable men of his generation and one of the biggest political men of our country.”
—William Howard Taft (1857–1930)
