Arthur Janszen was granted U.S. Patent 2,631,196 in 1953 for an electrostatic loudspeaker. The developers of the Tri-Ergon sound-on-film sound film system had developed a primitive design of electrostatic loudspeaker as early as 1919. Mr. Janszen's company, JansZen still makes an evolved version of his original design. The KLH Nine was designed in the mid-1950s by Arthur A. Janszen, and thousands were sold after the design was brought over to KLH in 1959 and put into regular production.
