History
In 1819 Wienerberger was founded in Vienna by Alois Miesbach and got its start making use of clay deposits in the Wienerberg area of Vienna. The company embraced innovations such as circular kiln designs, allowing it to have near-continuous production and achieve early success. Miesbach continued to increase manufacturing capacity as the business grew, and by the time of his death in 1857 the company had nine factories, a clay plant, and multiple coal mines. Miesbach's nephew, Heinrich Drasche, took over the company and maintained its dominant position.
