Even before 1900, he was experimenting with new ideas, like high-pressure stops with dual mouths on pneumatic cone valve chests. In 1906, he and his son Hans introduced electric action to organ building. When Hans took over in 1925, the company started embracing modern trends, particularly in facade design and more ergonomic console layouts. In 1965, Hans Gerd Klais (the founder's grandson, 1930-2026) became the third-generation leader, and later Philipp Klais took over as the fourth generation. Under Philipp's leadership, Klais has become one of the top organ builders worldwide, with projects in major churches and concert halls.
