" "Where to begin is obvious—with Michael Faraday... But we must proceed rapidly, jumping 70 to 80 years to [Alfred] Zehden (1902) and to Bachelet, then on to Kemper (1934) (surely the 'father' of Maglev), on again to Bedford, Peer and Tonks (1939) for induction levitation and finally to the Westinghouse 'Electropult' of 1946, the first high-speed linear motor ever to be built.

About Eric Laithwaite
Eric Roberts Laithwaite (14 June 1921 – 27 November 1997) was a British electrical engineer, known as the "Father of " for his development of the and maglev rail system. He and Fredrick Eastham designed a self-stable magnetic levitation system called (which incidentally appeared in the film The Spy Who Loved Me). Laithwaite derived an equation for "goodness", which parametrically described motor efficiency in general terms, and which he interpreted as implying that motor efficiency increases with size. He made many television appearances, including the to young people in 1966 and 1974. Laithwaite was also a keen amateur entomologist and the co-authored The Dictionary of Butterflies and Moths (1975).

Additional quotes by Eric Laithwaite
I know no property of a gyroscope that conflicts... with the conservation of energy. ... is in the same state today that as it was in the fifteenth century when Leonardo da Vinci denounced it so properly. ...If you really want to see perpetual motion, look into the sky on a cloudless night and marvel at the size and movement within the Universe.
[T]he textile men who dabbled in linear motors made a real contribution... and while they were probably unaware of each other's inventions, it seems probable that some of their work was known to later workers in other fields. If only some of the textile men had been aware of the potential for linear motors in those other fields, the 'Second Age of Topology'... might well have started earlier, just as the invention of the induction machine might have occurred in the 1830s had not the inventors of that time been blinded by the demand to generate 'battery-like' current.

The research director of Linear Motors Ltd told me in the late 1970s that he had then listed over one thousand different applications for linear motors. By this he meant that motors had been manufactured and sold for that number of different jobs. The most common applications included sliding doors, traveling cranes and conveyors. The items that were moved varied from 0.1 mg... to over 5 tonnes.
