In 1839 Herman J. Kähler immigrated to Næstved from Northern Germany. Shortly after his arrival, he started his own pottery in Næstved, where it all began. Kähler was a trained potter, and staying true to the old traditions, he stuck to production of articles for everyday use as milk dishes, soup pails, jam jars etc. However, he was best known for his production of all-night burners.
Kähler ran the company from 1839 to 1872. During that period he fathered seven children. When Herman Joachim Kähler retired in 1872, his sons Herman August Kähler and Carl Frederik Kähler took over the company, dividing the production between them. Carl Frederik continued the pottery production, while Herman August became the one who put Kähler ceramics on the world map.
