On the 100th birthday of Manfred Leisenberg †

For many years running, Manfred Leisenberg, born March 11, 1911, in ­Erfurt, helped shape the brick and tile industry with his ideas.

As a post-war pioneer, he liked to dabble in infinitely adjustable revolver presses and extrusion machines as weldments. At Bühler AG in Uzwil, Switzerland, he designed one of the first-ever plasticity control systems. That is also where the heavy oil pulse firing prototype was built. After going independent, Leisenberg specialized in firing technology. His new company soon took the lead in coal-to-oil changeovers, and he was among the first to introduce...
