Like his Rieger brother predecessors, Josef Glatter-Götz Jr. developed a new series of small organs. These were technical masterpieces and their popularity led to a renewed reputation and prosperity for the firm. Josef Jr. took full control of the firm after the death of his father in 1948. Under his direction, the firm returned decisively to the principles and traditions of the classical organ-building craft which had begun earlier in the century, while adding the modern benefits of advanced technology, tone, and design. More commissions came in from Germany, the United States, and Austria, and soon the workshops were too small.
