Gert & Hermien, a Dutch singing duo comprising Gert Timmerman and Hermien Timmerman-van der Weide, were a popular act particularly during the 1960s and 1970s in the Netherlands. Their musical journey together began after they married in 1963. Gert was already a known figure in the Dutch music scene as a solo artist, and with Hermien at his side, their collaborative efforts brought them greater fame.

Their sound was a melange of pop, Schlager, and later, Christian-themed music, which resonated well with a broad audience. The couple’s career highlights include chart-topping songs such as "Shalalie shalala (Alle duiven op de Dam)" and "Gert & Hermien Timmerman". Despite facing personal challenges and controversy in their later years, including a shift to religious music that was not as well received as their earlier work, the musical legacy of Gert & Hermien remains a cherished segment of Dutch popular music history. Their list of releases, including nostalgic compilations like "Het Beste Van" and seasonal albums like "Kerstfeest met Gert & Hermien", stands as a testament to their enduring appeal and contribution to the Dutch music landscape.
