    Check Wikipedia, the first was was introduced by Harry Ward Leonard 1891.
    I remember it back in the 50's.

    It was my understanding that the original W.L. system, although efficient, involved a great deal of machinery and floor space, with the advent of large power semi-conductor devices, electronic methods were devised enabling the same efficiency or better, and much more compact systems.
