Inspired by the work of Sven Carlson, Heinz Helmut Doevenspeck, a German engineer, was starting in 1958 to develop his so-called "Elektroimpulsverfahren", which used for the first time defined discharges of capacitors to generate homogeneous, pulsed electric fields. He applied these fields on dispersed systems of inorganic or organic origin to influence the membranes of plant or animal cells or the surface charges of particles. Cracking of cells, growing and/or killing of microorganisms, acceleration of fermentation processes and treatment of wastewater had been identified, described and patented by Doevenspeck as suitable applications already in the early 1960s. Until mid of the 1980s, working as an independent consultant, he did many trials at technical scale plants without reaching a breakthrough of his technology. From 1985 until 1993 he was cooperating with Krupp Company, Hamburg. In 1988 the first industrial scale plants were built and during this period several applications and process mechanisms were identified, mathematically modeled and presented to the scientific public for the first time.
