Michael Thonet’s sons, Franz, Michael junior, August, Josef and Jakob, joined the company Gebrüder Thonet in Vienna in 1853. After Michael Thonet’s death in 1871, they jointly managed the company. They developed new machines and work processes and presented numerous additional developments and new furniture designs. At around the turn of the century, the third generation of Thonets then became active in the company: Karl, Julius, Theodor, Alfred, Victor and Richard also designed a wide range of new furniture and products over the course of their activities.
